Medicine: USA U.S.Firm
to Unveil Cancer-Fighting Nanotechnology
By
Rebecca Lipchitz, The Sun, Lowell, Mass. Knight Ridder/Tribune
Business News
|

CHELMSFORD,
Mass. - A local company working with UMass Lowell
is getting ready for clinical trials on a nanotechnology-based
cancer
treatment for prostate and breast cancer.
"We're
getting a little too big for our incubator. We're about to
pop out of our shell," said Dr. Samuel Straface, CEO
of Triton BioSystems, which collaborated with UMass Lowell
to develop the treatment.
Representatives
from Triton and UMass Lowell, as well as U.S. Rep.
Marty Meehan were scheduled to unveil details during a press
conference Wednesday at Triton's Turnpike Road headquarters.
The
company uses technology developed by the Army to create a
two-part
cancer treatment in which bioprobes -- nanoscale magnetic
spheres
bound to an antibody -- are injected into the body. After
the bioprobes attach themselves to cancer cells, the doctor
activates the magnetic field, heating up the bioprobes and
killing the cancer cells within minutes.
UMass
Lowell scientists are working with Triton BioSystems to apply
the technology to treatment of other cancers, such as lung,
ovarian,pancreatic and renal cancers. U.S. Rep. Marty Meehan
secured a $1 million grant from the Department of Defense
to fund the project. The Army's research and development department
funds projects that use military technology for the advancement
of medical technology.
Straface
said the money will mostly be put toward the cost of putting
the new technology through clinical trials.
The
materials are expensive, and the U.S. Food and Drug Administration
has strict requirements for testing.
"There
are so many standards to meet, it's good for the patient,
but very expensive to reach (the market)," Straface said.Triton
BioSystems has spent about $5 million of mostly private money
on development of the technology since it opened two years
ago as an offshoot of Triton Systems. But the cost of development
in time and money has been cut in half by the partnership
with UMass Lowell,
Straface said.
"We
never could have done as much as quickly as we did without
that
partnership," he said. "It makes two plus two equal
five." |

Medicine: USA Nanotech
shows great promise on medical application
|
|
The
science of nanotechnology is rapidly moving from its early
beginnings in electronics, computersand telecommunications
into the expanding field of nanomedicine.
The
emerging nanomedicine has the potential to change medical
science dramatically in the 21st century, scientists said
at the annual meeting of the American Association for the
Advancement of Science (AAAS) in Seattle.
When nanotechnology started in the mid-1990s, it was mainly
used to produce smaller and faster semiconductor chips. But
in thepast two years, a number of breakthroughs were reported
on using the technology to diagnose and treat human diseases.
Nanotechnology works at the atomic and molecular levels, equivalent
to 1/100,000th the diameter of human hair.
Nanomedicine integrates technology, biology and medicine,
usingtools and materials constructed from molecular and atomic-sized
particles too small to be seen with a conventional laboratory
microscope, according to Dr. Shuming Nie, professor of biomedical
engineering at Emory University and the Georgia Institute
of Technology.
Speaking at the nanotechnology forum of the AAAS meeting,
Dr. Nie said although nanoparticles are similar in size to
biomolecules such as proteins and DNA (deoxyribonucleic acid),
they can be humanly engineered to have specific or multiple
functions.
Medical applications for nanoparticles will focus on cancer,
cardiovascular disease, and neurodegenerative diseases, such
as Alzheimers, said Dr. Nie.
The most elementary nanomedical devices will be used to diagnose
illness. Mobile nanorobots, equipped with wireless transmitters,
might circulate in the blood and lymph systems and send out
warnings when chemical imbalances occur or worsen.
Similar nanomachines could be planted in the nervous system
to monitor pulse, brain-wave activity, and other functions.
Scientists at the Georgia Institute of Technology have recently
developed a tiny nanorobot called "nanospring" structure,
which could detect individual molecules and possibly create
an extremelysensitive method of detecting cancer.
When the "nanospring" structure encountered even
a single cancer-protein molecule, it would send a radio signal
through the skin, the researchers said.
More advanced use of nanotechnology might involve nanoparticles
to dispense drugs or hormones as needed in people with chronic
imbalance or deficiency states.
US scientists have developed semiconductor nanoparticlescalled
quantum dots, which can be bound to particular genes and proteins
and deliver drug.
The most exciting nanomedicine is nanorobots working as miniature
surgeons, which might repair damaged cells, or get inside
cells and replace or assist damaged intracellular structures.
At the extreme, nanomachines might replicate themselves or
correct genetic deficiencies by altering or replacing DNA
molecules.
The American National Science Foundation estimates that the
nanomedicine market could be worth 1 trillion US dollars by
2015.Nanomedicine is a priority in the recently released new
Roadmap of the US National Institute of Health.
US President George W. Bush signed the 21st Century Nanotechnology
Research and Development Act in December, which invests 3.7
billion dollars over four years starting fiscal year 2005
in research and development programs of nanotechnology. More
than half of the money will go to nanomedicine.
But some scientists stressed at the AAAS meeting that it will
take 20 to 30 years before people have nanomedical products
in their hands.
"That
puts us at 2020 or 2025, before nanoscience really becomes
part of your life," said Dr. Yi Cui from University of
California, Berkeley. Enditem |

A
SILICON microrobot just half the width of a human hair has

This distinctly futuristic development could lead to muscle-based

The
Arlington Institute will sponsor a two-day seminar examining
"Breakthrough Technologies for the World’s Biggest Problems,"
to be held April 27-28 in Arlington, Virginia. The seminar
will feature Ray Kurzweil, Hunter Lovins, Eric Drexler, and
others invited to speak about the big problems and opportunities
in the coming years. A collection of extraordinary breakthrough
technologies for solving
global problems will also be showcased.
"The
future of humanity is inextricably linked to technology,"
says John L. Petersen, president of the Arlington Institute.
"The future of the globe pivots on the kinds of tools
we do or do not create in the coming years. Enlightened people
with old tools will be significantly limited in what they
can do to change the planetary footprint. We have to learn
how to utilize new breakthrough technologies to solve our

Products: PhoeniX
B.V release FlowDB and OperatorDB
|
|
The
Netherlands: PhoeniX B.V. is proud to announce the release
of FlowDB and OperatorDB. These products are developed for
the micro and nano technology market. FlowDB is developed
to design hierarchic process flows. OperatorDB uses these
process flows in manufacturing to gather data from the actual
process.
Features of FlowDB:
· Hierachic design of process flows
· Reuse of designs
· Version control
· Arbitrary abstraction levels
Features of OperatorDB
· Interactive logbook facilities
· Active batch control
· Basis for statistical process control
The products can be used as standalone modules. Combining
both, however, opens the possibility of using actual data
from the factory in new process flow designs. Due to the standardization
of information the communication between designers, process
engineers and operators is always fast and correct.
Niels
Olij (Project leader):"The process related information
generation within the micro and nano technology market is
very immature. In IC industry comparable tools are available
but these are expensive and rather static. That is why most
companies and institutes in micro and nano technology currently
rely often on in-house solutions; mainly developed due to
a lack of professional tools. These internal solutions seem
to be cheap and fit internal needs; changing requirements,
support and training does make these tools expensive and inflexible
though."
Arjen
Bakker (CTO):Data storage in a database nowadays is very common
practice for all kinds off applications. FlowDB and OperatorDB
distinguish themselves by being the first to address real-life
cleanroom issues. Being able to (re)use measured data during
the design phase of new components or improvements on current
design, also reduces "time to market" considerably.

MASS DETECTION

|
ATTOGRAM
MASS DETECTION has been achieved by Harold Craighead and
his colleagues at Cornell, with prospects of exquisite detection
of
very tiny chemical and biological species, possibly with arrays
of
detectors. With their lithographically fabricated nanoelectromechanical
(NEMS) device, the Cornell researchers can measure the mass
of a particle with a sensitivity of 10^-18 grams, far exceeding
the precision of a comparable device with femtogram (10^-15
g) sensitivity reported last yearTo get any better measurement
of mass you would have to vaporize the particle and shoot
its constituent molecules through a mass spectrometer.
At
Cornell, mass measurement works this way: when the minuscule
particle is absorbed onto a tiny sliver of silicon it alters
the sliver's resonant oscillation.The oscillation in turn
is monitored by reflecting laser light off the cantilever.
It's as if a particle with a mass of a billionth of a billionth
of a gram stepped onto a diving board whose springiness was
observed by reflected light. So far Craighead's group has
weighed small gold dots and tiny coatings of molecules on
the dots, but the goal is to detect and identify viruses.
(Previously the same group detected the immunospecific binding
of a single bacterium using the
oscillating-cantilever method.
They
did this by coating their with a specific antibody and therefore
could bind and detect the added mass only of the corresponding
antigen.) The mass sensitivity with the present cantilever
(4 microns long, 500 nm wide, and at room temperature) is
expected to be 0.39 attogram and will only get better as the
size of the cantilever is reduced further, extending the sensitivity
well into the zeptogram (10^-21 g) range.

Pioneers Predict Nanomedicine Impact within Five Years
|
|
With
nanobiotech research growing at an astounding rate -- and
funds starting to follow – what are the most promising near-term
prospects for nanomedicine?
Predicting which applications will have the resources -- and
luck --to succeed is a dicey proposition, experts acknowledge.
But NanoBiotech News posed the questions to the field's preeminent
pioneers and found that real-world applications of nanomedicine
will happen within five years.
Ground-breaking
nanotechnology researcher Ralph C. Merkle, Ph.D., and the
father of nanomedicine Robert A. Freitas, Jr., JD, are among
the industry heavyweights who weighed in with NanoBiotech
News on the state of the science and where it's headed.
"Broadly
speaking, we are entering a new era in which we can manipulate
molecular structures with greater precision," Merkle
tells NanoBiotech News.
In
some ways, nanomedicine has already entered the clinic in
the form of magnetic nanoparticles used as targeted contrast
agents for MRI and optical imaging, says Erkki Ruoslahti,
Ph.D., MD, professor at The Burnham Institute in La Jolla,
CA.
"These
show all kinds of promise, not only for diagnostics but for
therapeutics," says Ruoslahti, who has conducted seminal
research on targeting nanoparticles in vivo.
"The
evolutionary spectrum in nanomedicine will start at the sensing
and diagnostics end and move into therapeutics over time,"
predicts Freitas, research fellow at the Institute for Molecular
Manufacturing
and author of Nanomedicine, the first book-length technical
discussion of the medical applications of nanotechnology and
medical nanorobotics.
Diagnostic
applications are on a faster track simply because the clinical
trials hurdles are fewer and easier, observes Jennifer West,
Ph.D., assistant professor in the Department of Bioengineering
at Rice
University in Houston and a leading researcher on the use
of gold nanoshells. "Scientifically, it makes sense to
go for in vitro diagnostics, such as blood tests, and we'll
see some nice applications
in diagnostics in the next two to five years."
Freitas
adds, "Most of my work is oriented toward the longer
term, but if I had to guess, the applications nearest to commercialization
are probably the fullerene-related and dendrimer-related drugs,"
Freitas
says. "The nanoshells are making their way toward commercialization,
but the fullerenes and dendrimers are probably closest in
terms of somebody making money from a product."

field by reading NanoBiotech News every week. Every major
nanomedicine development -- from both business and scientific
perspectives -- is covered in this global nanobiotechnology

CLONING:
SCIENTISTS IN SOUTH KOREA CLONE MATURE HUMAN EMBRYOS.

was a year ago that Clonaid Inc., owned by Raelians, announced
the cloning of baby Eve (WN 3 Jan 03). Raelians believe the
first humans were cloned by space aliens. (Ever notice how
funny other people's religions are?)
That was a hoax, but this looks like a real breakthrough in
therapeutic cloning. Embryonic stem cells with the same DNA
as a donor mother were derived. In spite of great medical
promise, it's already stirring up controversy in the Senate,
which is deadlocked on whether to ban such research.
But whatever we do in the U.S., it now seems inevitable that
reproductive cloning of a human will happen sometime, somewhere.

be used in many applications, including sensors and other

One recent example is a chemical system devised at Sandia
National Laboratory (Albuquerque, N.M.) that creates a wide
variety of complex nanostructures from platinum. The system
uses the porphyrin molecule, a protein essential to photosynthesis,
as a catalyst for depositing platinum on small organic structures

CONTROLLING
MATERIAL STRUCTURE AT NANOSCALE MAKES BETTER THERMAL INSULATOR
Heat
may be essential for life, but in some cases - such as protecting
the space shuttle or improving the efficiency of a jet engine
- materials with low thermal conductivities are needed to
prevent passage of too much heat. As reported in the Feb.
13 issue of the journal Science, researchers have created
a better thermal insulator by controlling material structure
at the nanoscale.
"We
explored ways to control thermal properties in materials by
introducing structure on nanometer length scales," said
David Cahill, a professor of materials science and engineering
and a Willett Faculty Scholar at the University of Illinois
at Urbana-Champaign. "By making nanolaminates of dissimilar
materials, we found that we could significantly decrease the
thermal conductivity because heat
cannot be carried efficiently across the material interfaces."
Cahill,
graduate student Ruxandra Costescu and colleagues at the University
of Colorado at Boulder first synthesized thin-film nanolaminates
composed of alternating layers of tungsten and aluminum
oxide using atomic layer deposition and magnetron sputter
deposition. Cahill and Costescu then measured the thermal
conductivity of the nanolaminates using a technique called
time-domain thermoreflectance.
"The
reflectivity of a metal is a very subtle function of its temperature,"
Cahill said. "By measuring how fast the reflectivity,
and therefore the temperature, changes over time, we can determine
the thermal conductivity."
To
measure the temperature of such small samples, the researchers
use an ultra fast, mode-locked laser that produces a series
of subpicosecond pulses. The laser output is split into a
"pump" beam
and a "probe" beam. The pump beam heats the sample
and the probe beam measures the reflectivity, and hence the
temperature.
"By
making the individual layers only a few nanometers thick,
we produced a nanolaminate material that had a thermal conductivity
three times smaller than a conventional insulator," Cahill
said. "The high interface density produced a strong impediment
to heat transfer."
Heat
flow from one material to another is limited at the interface,
Cahill said. Heat is carried by vibrations of atoms in the
lattice, and some of these lattice vibrations are scattered
at the interface and don't get transmitted across the interface.
"In
our nanolaminates, vibrations in one material don't communicate
well with those in another," Cahill said. "The heavy
tungsten atoms are vibrating fairly slowly, but the light
aluminum oxide atoms are vibrating quickly. The differences
in elastic properties and densities of vibrational states
inhibit the transfer of vibrational energy across the interface."
The
experimental results suggest that materials engineered with
high interface densities may provide a route for the production
of thermal insulators with ultra-low thermal conductivities.
The
researchers' findings also have some surprising implications
for nanomaterials that are intended to perform as high thermal
conductors in applications such as dissipating heat from electronic
circuits or
sensors. For example, carbon nanotubes - which have been shown
to have extremely high thermal conductivities - will not perform
well as fillers in composite materials designed to improve
thermal transport.
"Nanotubes
do not couple well thermally to the surrounding material,"
Cahill said. "As a result, the heat transport across
the nanotube-matrix interfaces will be very limited."…read

Medicine: Nano
in Medicine, and its socio-economic implications in Europe
Nanotechnology
In medicine, innovative devices can be developed by arranging
atoms in small numbers, almost one by one. Nanotechnology
works on a level as small as a millionth part of a millimeter.
Tools operating on this tiny scale open possibilities for
diagnosis, imaging and implantation that are not thinkable
of with conventional techniques.
The
EuropeanUnion sponsored network Nanoforum fosters nanotechnology
and recently published a report on socalled "smart materials"
for medical devices. Such materials are able to help, for
example, selecting single cells from blood samples, or to
label drug molecules in order to follow their path from the
blood into the brain. Apart from these diagnostic purposes,
advanced applications as retina implants are seen as well:
miniaturised electrodes stimulate the retina cells in the
eye and promise to restore a good deal of sight in blind patients.
The
report focusses on the social and economic aspects of this
new branch of technology, and is complemented with vived examples
of current developments. Researchers from Germany, UK, Scandinavia
and other countries are interviewed and highlight the pros
and cons of the techniques they develop.
The

to this 139 billion euros market. National programmes and
networks in a number of active countries are presented too.

Computer
scientists develop tool for mining genomic data
Equipped
with cutting-edge techniques to track the activity of tens
of thousands of genes in a single experiment, biologists now
face a new challenge - determining how to analyze this tidal
wave of data. Stanford Associate Professor of Computer Science
Daphne Koller and her colleagues have come to the rescue with
a strategic approach that reduces the trial-and-error aspect
of genetic sequence analysis.
``What
we`re developing is a suite of computational tools that take
reams of data and automatically extract a picture of what`s
happening in the cell,`` says Koller. ``It tells you where
to look for good biology.``
Koller
presented her statistical approach for mining genomic data
at a Feb. 14 symposium - ``Machine Learning in the Sciences``
- at the annual meeting of the American Association for the
Advancement of Science (AAAS) in Seattle.
Several
years ago, before Koller came onto the scene, a new generation
of high-throughput assays revolutionized molecular biology.
In the most stunning example of this technology, scientists
began using thumbnail-sized ``gene chips`` to monitor the
activities of thousands of genes at once. In October 2003,
Santa Clara-based Affymetrix took this breakthrough to a new
level when it began marketing whole-genome chips packed with
all 30,000 to 50,000 known human genes. Genome chips can reveal,
for instance, that in kidney cells treated with a certain
drug, 116 genes spring into action while another 255 get shut
off.
But
this state-of-the-art DNA microarray technology provides only
a single snapshot of the cell. ``It`s a very partial view,``
Koller says.
What
scientists really want to know is how groups of genes work
together to control specific biological processes, such as
muscle development or cancer progression. Unraveling these
regulatory networks - for example, determining that Gene A
gets activated by Gene B but repressed by Gene C - is a daunting
task.
Sifting
through whopping amounts of DNA microarray data to cull the
hundreds of activator and repressor candidates is actually
the easy part. The real challenge is figuring out which of
these genes, if any, are biologically meaningful. This requires
a bewildering array of hit-or-miss wet-lab experiments that
examine protein-protein and protein-DNA interactions among
the candidate genes.
Koller`s
computational tools will make this scheme less formidable
by providing scientists with targeted hypotheses in the form
of ``Gene A regulates Gene B under Condition C.`` These predictions
are generated from a probabilistic framework that integrates
data from a variety of sources, including microarrays, DNA
sequences, and protein-protein and protein-DNA interactions.
As
Koller sees it, each of these sources offers a glimpse into
what is happening in the cell: ``a snapshot from this angle,
a shot from another angle, data from a third, and so on.``
Her computational scheme creates ``the best picture we can
construct from putting all of these snapshots together.``
The
proof of concept for Koller`s targeted hypotheses came in
a June 2003 Nature Genetics publication, which described the
application of her tools to predict gene regulatory networks
in a variety of biological processes in yeast. Three of these
predictions were confirmed in wet-lab experiments, suggesting
regulatory roles for previously uncharacterized proteins.
``The
creativity and computer science perspective brought to these
problems by Koller and her collaborators provide a tremendous
boost to biology,`` says Matthew Scott, a developmental biologist
at Stanford and chair of the scientific leadership council
of Bio-X, an interdisciplinary initiative. His research group
has used Koller`s approach to identify genes involved in specific
processes during embryonic development, to determine which
genes are key regulators of other genes and to track changes
in gene activities during disease progression.
Scott
adds that while the computational methods suggest interesting
hypotheses, their ultimate validation relies upon lab experiments.
In
the future, Koller hopes to develop her scheme to handle multi-species
analysis - for instance, to identify gene regulatory networks
that appear in both human and mouse genomes. ``When a regulatory
module is conserved across multiple species, that indicates
it`s playing a significant role,`` Koller says.
Koller`s
collaborators include Eran Segal and Michael Shapira (both
of Stanford), Nir Friedman (Hebrew University of Jerusalem),
Aviv Regev (Harvard Center for Genome Research), Dana Pe`er
(Harvard-Lipper Center for Computational Genetics), Roman
Yelensky (Massachusetts Institute of Technology) and David
Botstein (Princeton University)….read

Technology Company Tripled Turnover
The
Berlin-based technology company Capsulution NanoScience AG
can look back onto a very successful year after it tripled
turnovers during the second half of 2003. According to a preliminary
balance at the end of the second half of last year the Company
was able to generate operational profits of some 45,000 euros
compared with operational losses of some 585,000 euros during
the first half of 2003.
Following
the company's shake-up that was started last summer the overall
performance during the financial year 2003 has been considerably
better than expected. Based on the continuing development
of innovative nanoproducts for numerous industrial applications
and thanks to the acquisition of several renowned partners
and clients during the course of last year Capsulution expects
another substantial increase in turnovers for the current
year and looks forward to breaking-even.
Alexander
Herrmann, Chief Financial Officer of the Berlin-based company,
commented very optimistically on the new financial year: "Despite
our primary goal of becoming profitable we are continuing
on the path of our vision, to apply our proprietary resources
in laying the foundations for the introduction of our technology
to new areas of application. In this respect we are very confident
that also in 2004 we will be able to convince new industry
partners of the versatility and benefits of our nanotechology.
Additionally we are committed to offering interested financiers
continual opportunities to invest in the successful progression
of our technology and to participate in the value creation
of our company."

PURDUE
RESEARCHERS CREATE DEVICE THAT DETECTS MASS OF A SINGLE VIRUS
PARTICLE USA:
Researchers at Purdue University have developed a miniature
device sensitive enough to detect a single virus particle,
an advancement that could have many applications, including
environmental-health monitoring and homeland security.
The
device is a tiny "cantilever," a diving board-like
beam of silicon that naturally vibrates at a specific frequency.
When a virus particle weighing about one-trillionth as much
as a grain of rice lands on the
cantilever, it vibrates at a different frequency, which was
measured by
the Purdue researchers.
"Because
this cantilever is very small, it is extremely sensitive to
added mass, such as the addition of even a single virus particle,"
said Rashid Bashir, an associate professor of electrical and
computer engineering and biomedical engineering.
Findings
are detailed in a paper to appear next month in Applied Physics
Letters, a journal published by the American Institute of
Physics. The paper, which is likely to appear in the weekly
journal's
March 8 issue, was written by doctoral student Amit Gupta,
senior research scientist Demir Akin and Bashir, all in Purdue's
School of Electrical and Computer Engineering.
The
work, funded by the National Institutes of Health, is aimed
at developing advanced sensors capable of detecting airborne
viruses, bacteria and other contaminants. Such sensors will
have applications in areas including environmental-health
monitoring in hospitals and homeland security.
"This
work is particularly important because it demonstrates the
sensitivity to detect a single virus particle," Gupta
said. "Also, the device can allow us to detect whole,
intact virus particles in real
time. Currently available biosensing systems for deadly agents
require that the DNA first be extracted from the agents, and
then it is the DNA that is detected."
The
next step will be to coat a cantilever with the antibodies
for a specific virus, meaning only those virus particles would
stick to the device. Coating the cantilevers with antibodies
that attract certain
viruses could make it possible to create detectors sensitive
to specific pathogens.
"The
long-term goal is to make a device that measures the capture
of particles in real time as air flows over a detector,"
Bashir said.
Scientists
are striving to create "lab-on-a-chip" technologies
in which miniature sensors perform essentially the same functions
now requiring bulky laboratory equipment, saving time, energy
and materials.
Thousands
of the cantilevers can be fabricated on a 1-square-centimeter
chip, Akin said.
The
Purdue researchers used the device to detect a particle of
the vaccinia virus, which is a member of the Poxviridae family
and forms the basis for the smallpox vaccine.
The
cantilever is about one micron wide - or about one-hundredth
the width of a human hair - 4 microns long and 30 nanometers
thick. A nanometer is a billionth of a meter, or roughly the
length of 10 hydrogen atoms strung together.
"This
cantilever mechanically resonates at a natural frequency,
just like anything that vibrates has a natural frequency,"
Bashir said. "What we do is measure the natural frequency
of the cantilever, which
is a function of its mass. As you increase the mass, the frequency
decreases. And the way to increase the sensitivity is to make
that starting mass very, very small."
A
single vaccinia virus particle weighs about 9 femtograms,
or quadrillionths of a gram.
"So,
if a grain of rice weighs a couple of milligrams, one of these
virus particles weighs about one-trillionth as much,"
Bashir said.
Because
the cantilevers are mechanical parts measured primarily on
the scale of microns, or millionths of a meter, they are called
"micromechanical devices."
The
researchers created the cantilever using the same technology
used by the semiconductor industry to etch circuits in electronic
chips. Silicon is deposited as a blanket onto the surface
of a wafer and then formed into patterns during numerous steps,
including chemical etching. In this case, a cantilever is
formed instead of a circuit.
In
addition to funding from NIH, facilities in Purdue's
Birck Nanotechnology Center were used to carry
out the experiments.

RULE-BREAKING' MOLECULE COULD LEAD TO NON-METAL MAGNETS
WEST
LAFAYETTE, USA Purdue University scientists have uncovered
an unusual material that could lead to non-metallic magnets,
which might be lighter, cheaper and easier to fabricate than
magnets made of metal.
A
team of researchers, including Paul G. Wenthold, has analyzed
a radical hydrocarbon molecule whose electrons behave differently
than they should, according to well-known principles. The
compound is not the only molecule that exhibits such odd behavior
in its surrounding cloud of electrons, but it is the first
to be discovered that does not include a transition metal.
"In
that respect, this is a unique exception to the electron-behavior
rule, and it might help chemists think more clearly about
where other exceptions lie," said Wenthold, an assistant
professor of chemistry in
Purdue's School of Science. "Designing materials with
novel properties depends on understanding the forces at work
inside their molecules, and understanding the structure of
this exceptional molecule could lead to new tools for material
design."
The
research, which Wenthold conducted with Anna I. Krylov of
the University of Southern California and members of both
their research groups, appears in today's (2/ 2) issue of
Angewandte Chemie International Edition, a major European
chemistry journal. The team deduced the structure of the compound
using advanced techniques, including mass spectrometry.
Radical
molecules, which contain unpaired electrons and are thus more
reactive than molecules without them, have gained household
notoriety primarily because so-called "free radicals"
in the bloodstream can
damage healthy cells. While the molecule Wenthold's team has
investigated is not found in the body and has no household
name - it is referred to only by its chemical description,
5-dehydro-1,3-quinodimethane - it has a property that would
raise the eyebrows of any observant student in a first-year
chemistry course. The surprise stems from the uncommon way
its three unpaired electrons arrange themselves around the
nuclei in the molecule's atoms - an arrangement that students
learn is virtually fundamental.
"It's
called Hund's Rule," Wenthold explained. "It says
that unpaired electrons line up facing the same direction
when they arrange themselves around the molecular center.
You might think of them as
three-ring binders lying flat on shelves: You want to be able
to read the labels on all of their spines, so you lay each
binder flat with its spine pointing outward."
Paired
electrons, he explained, would resemble two binders stacked
one atop another; if their spines were both facing the same
way, the top face of the upper binder would not form a flat
surface, and it would tend to slide off the lower binder.
None of a radical's unpaired electrons is constrained by this
need to face the opposite direction, as they all have their
own "shelves," or quantum energy levels.
"Nonetheless,
one of the three unpaired electrons in our molecule faces
the opposite direction," Wenthold said. "Since this
is the first time we've ever seen this happen in an organic
triradical, it opens up a few
new possibilities for materials designers."
Krylov
said the possibilities might include the building blocks for
molecular magnets.
"People
are already trying to build magnets from materials other than
metals, such as the polymers that form plastic," she
said. "Since magnetism is related to the behavior of
unpaired electrons, this compound could be used as a building
block for such polymers, leading to non-metallic magnets.
It could extend a materials scientist's options."
The
National Science Foundation (NSF)'s Tyrone Mitchell said that
non-metallic magnets might have significant advantages over
metal ones.
"Non-metal
magnets would have several conceivable advantages," said
Mitchell, who is program director in the NSF's chemistry division.
"If we can find ways to magnetize hydrocarbons, for example,
they would weigh less than metallic magnets, making them attractive
to the space program and other commercial applications in
which weight is always a concern. And since the raw materials
would also be cheaper and easier to fabricate than metal substances,
such magnets could conceivably save
money in the long run."
Wenthold
and Krylov cautioned that such possibilities are only speculation
for the moment, and for now the major significance of the
find is the fundamental knowledge it provides.
"We
still have a lot to learn about molecules such as this one,"
Wenthold said. "We have a long list of steps that will
follow this one, such as comparing this molecule's properties
with one that does not
have its unpaired electrons facing different directions. But
the unique property this substance exhibits will be of interest
in its own right, even before we come up with any actual applications
for it. It is one
thing to discover magnets - designing them is far more difficult
and requires an understanding of what makes them magnets in
the first place."

CARBON NANOTUBE GEL,
the first example of a liquid crystalline material consisting
of single-walled nanotubes, has been made by physicists
at the University of Pennsylvania. Basically the gel is
a mass of half-micron long nanotubes, aligned like little
logs along a single direction, in a polymer matrix. The
gel exhibits hallmark properties of a nematic liquid crystal
(in which rod shaped molecules are aligned) including optical
anisotropy (birefringence) and topological defects. The
gel's anisotropic characteristics and its sensitivity to
changes in solvent quality might make it a candidate for
novel applications. It could be useful, for example, as
an osmotic or an electrical actuator in which changes in
electrical field or salt concentration produce volume and
shape changes. The gel was made by coating the nanotubes
with surfactant chemicals and mixing in polymers which form
a cross-linking network among the tubes. Next the volume
was compressed. The resultant densities of isolated single-wall
nanotubes are higher than can be produced in simple aqueous
suspensions. (Islam et al., Physical Review Letters, upcoming

DUPONT DONATES NANOTECHNOLOGY PATENTS
The
University of California, Davis, College of Engineering has
received a collection of patents and other intellectual property
from DuPont on using nanotechnology to generate electron beams.
The donation will support work in the Vacuum Microelectronics
group led by Charles E. Hunt, professor in the Department
of Electrical and Computer Engineering.
The
donation includes: eight granted U.S. patents and current
U.S. patent applications on field-emission vacuum microelectronics;
multiple foreign patents and pending applications; other company
technical information; support equipment; and funds to support
graduate student research in Hunt's laboratory.
Hunt's
laboratory applies nanotechnology to build tiny structures,
hundreds of times smaller than the thickness of a human hair,
that can confine enormous electric fields in a very small
volume of material. This material then emits electrons that
can be focused into a beam. These "field-emission"
devices have numerous emerging applications ranging from high-efficiency
lighting to novel biomedical devices, nanoscopic X-ray sources,
cathode ray tubes and microwave devices, Hunt said.
The
UC Davis researchers will be able to develop and add to the
existing patents and license them to other companies or to
startup companies spun off from UC Davis. Any future royalties
or licensing fees will benefit the University of California.
"We
are immensely pleased by the generous donation from DuPont,"
said Enrique Lavernia, dean of the College of Engineering
at UC Davis. "It allows us to build on an area in which
the college already excels,and it is a vote of confidence
on the part of an important industrial partner in our ability
to make the best possible use of the patents. We know that
our researchers in the Department of Electrical and
Computer Engineering are poised to build on this gift.

Researchers
in Colorado (USA ) have discovered a new form of atomic matter,
a fermionic condensate unlike anything seen before.
To
approach this conceptually-difficult but physics-rich topic,
we will proceed in several parts: providing a quantum background,
defining the word "degeneracy," summarizing the
new atomic state, and finally
assessing the advantages of the new state.
1.
Quantum background. In exploring the exotic landscape ofquantum
gases, physicists have lavished much attention on bosonicatoms
(atoms whose total spin has an integer value, such as 0 or
1or 2). In 1995 scientists succeeded in cooling (bosonic)
atoms sothat in a quantum sense the atoms began to overlap,
at which pointthey really could not be distinguished and had,
in effect, becomepart of a single quantum entity called Bose
Einstein condensate(BEC). Fermions (possessing half-integer
spins, such as 1/2 or 3/2
or 9/2), whether elementary particles like electrons and quarks,
orwhole atoms (and in determining whether an atom is a boson
orfermion one has to add up the spins of all its constituent
protons,neutrons, and electrons), do not act like bosons.
The Pauliexclusion principle dictates that no two identical
fermions may occupy the same quantum state. Most of chemistry
here on Earth andelsewhere is dictated by the simple Pauli
rule: electrons fillatomic orbitals in such a way that no
two electrons have exactly thesame quantum values. Partially
filled orbitals determine what kindof chemical affinity that
atom will have. Note that fermion atomsare not precluded from
interacting in ordinary chemical reactions(the atoms have
differing nuclear and electronic internalc onfigurations).
But they may not enter into an extensive BEC kind of quantum
condensate where the atoms do possess the same quantum attributes.
2.
Degeneracy. Pauli is on duty at all times, but he chieflymanifests
himself in a quantum setting, such as in the orbitalswithin
an atom or in the chilled molasses of a microkelvin-levelatom
trap. In this rarefied realm, bosons can all fall into that
singular BEC state. All having the same energy, these atoms
are
said to be degenerate. With fermions, it's quite different.
In aquantum setting---whether electrons moving through a crystal
or fermion atoms chilled in a trap, fermions are obliged to
fill, one by one, all the different possible quantum energy
states, starting at the low end. On an energy level diagram,
the fermions look as if they were perching on the rungs of
a ladder, filling all the rungs singly. (The uppermost rung
is called the fermi energy and the temperature that corresponds
to that energy is called the fermi temperature.)
Commonplace
example: the free-roaming electrons in a metal crystal, even
at room temperature, are obliged to assume a set of discrete
quantum-allowed energies in this way. These electrons are
said to constitute a degenerate fermi gas. In the fermion
context, "degenerate" means that the particles fill
up the plenum of possible energy states. Creating such a gas
of degenerate fermion atoms proved more difficult to make
than a degenerate (BEC) gas of boson atoms. In fact, a degenerate
fermi gas was first accomplished
only in 1999 (www.aip.org/enews/physnews/1999/split/pnu447-1.htm)
in an experiment by Deborah Jin and her NIST/JILA colleagues,
the same lab where the new results have been performed. By
the way, although
physicists had long assumed the Pauli principle would apply
to atoms (composite objects) as well as to electrons (truly
elementary particles), it was only in recent work that this
was demonstrated experimentally.
3.
New state of matter. Fermions, if you pair them, can become
bosons. And in that way, fermions can enter pairwise into
a quantum condensate. There are, however, a whole spectrum
of pairing mechanisms. At one extreme is the case where the
atoms pair strongly, after which they can (as molecules) collapse
into a Bose Einstein condensate (BEC). At the other end of
the spectrum the atoms can pair weakly, or more to the point,
combine in an unbound but correlated state analogous to the
Cooper pairs of electrons that form the essence of quantum
currents in superconductors or the pairs of helium-3 atoms
that constitute a superfluid. In previous months a number
of labs have reported forming condensations of
strongly-bound molecules
(see
www.aip.org/enews/physnews/2003/split/663-1.html
). Now Deborah Jin and her colleagues Cindy Regal and Marcus
Greiner at NIST and the University of Colorado report making
great progress in moving across the plain between the BEC
and BCS pairing alternatives. The type of pairing can be adjusted
by subtly altering the strength of an external magnetic field.
The NIST researchers, who cool potassium-40 atoms to microkelvin
temperatures, are at the cross-over region: they are not at
the BEC regime because the applied magnetic field would not
permit the kind of pairing one needs for a BEC condensate.
Also they can affirm that they are not in the BCS regime either
because the strength of the interaction among atoms is too
strong for the kind of weak Cooper pairing that occurs in
superconductivity or helium-3 superfluids.
This
new condensed form of atomic matter should not be thought
of merely as a way station between the BEC and (weak) BCS
pairing alternatives, but as a unique state in its own right.
Eric Cornell (also at NIST but not part of Jin's group), who
won a Nobel prize for his part in the discovery of BEC, describes
the new NIST state as "a dramatic new sort of fermionic
condensate, basically Cooper pairing in the strong-field limit."
4.
Assessment. One of the goals in pursuing this research is
the chance to form novel types of Cooper pairs or superfluids,
and possibly to custom make different kinds of superconductivity.
In these cold fermi gases the interactions (and the strength
of the pairing) can be adjusted by turning a knob (changing
the magnetic field), which is more than you can say about
conventional superconductivity, metallic or ceramic. Here
is one hint that this work might lead to warmer, even room
temperature, superconductivity: In the new potassium fermionic
condensate the ratio of transition temperature (at which condensation
of pairs
occurs) to fermi temperature is about 1 to 5. In conventional
low-temp superconductors the ratio is 1 to 1000 (or even 100,000).
Even
in high-temp superconductors, the ratio is 1 to 100. (Regal
et al., Physical Review Letters, 30 January 2004; additional
background in Physics Today, Oct 1999 and Oct 2003.)

Dazzling
new light source opens at Stanford Synchrotron Radiation Laboratory
``The light shines brilliantly these days at the Stanford
Synchrotron Radiation Laboratory (SSRL),`` said U.S. Secretary
of Energy Spencer Abraham. ``The start-up of SSRL`s new synchrotron
light facility, SPEAR3, guarantees a world-class program in
x-ray science for years to come.``
SPEAR
stands for Stanford Positron Electron Asymmetric Ring. SPEAR3
was formally opened at a dedication ceremony at the Stanford
Linear Accelerator Center (SLAC) on Jan. 29. It incorporates
the latest technology - much of it pioneered at SSRL and SLAC
- to make it competitive with the best synchrotron sources
in the world.
Some
2,000 scientists from around the country will use SPEAR3`s
extremely bright x-ray light each year to illuminate the long-kept
secrets of materials, chemical and biological matter.
Synchrotron
light has revolutionized our view into the sub-microscopic
world and has contributed to major innovations in fields such
as solid-state physics, materials science, environmental sciences,
structural biology and chemistry. Synchrotron light is created
when electrons traveling the speed of light take a curved
path around a storage ring, a structure in which high-energy
particles can be circulated many times and thus ``stored.``
The electrons emit electromagnetic light in x-ray through
infrared wavelengths. The resulting light beam has characteristics
that make it ideal for revealing the intricate architecture
and utility of many kinds of matter.
``This
facility will be crucial to advancing the field of structural
biology, which is growing in importance to the NIH [National
Institutes of Health] mission, by enabling cutting-edge targeted
drug design projects and major efforts such as the Protein
Structure Initiative and the Structural Biology arm of the
NIH Roadmap,`` said Dr. Elias Zerhouni, NIH director. ``From
its very genesis as a joint project between NIH and DOE [Department
of Energy], this new facility exemplifies the collaborative
nature of science and the productive cross-fertilization between
biological and physical disciplines.``
Said
SSRL physicist John Arthur: ``SPEAR3`s brilliant x-ray beams
provide the ability to study smaller objects at higher resolution.
In many cases the greater brightness at SPEAR3 will also enable
researchers to take their data faster, do more difficult experiments
and use smaller samples of material.``
Noted
Abraham: ``This is the first time the Department of Energy
and the National Institutes of Health have joined in funding
an accelerator research facility.``
Thirty
years ago, SSRL was among the first laboratories in the world
to use synchrotron produced x-rays for studying matter at
atomic and molecular scales, and the first to offer beam time
to a broad community of scientists from academic, industry
and government labs submitting research proposals for peer
review. The original SPEAR ring, built for particle physics
programs at SLAC, yielded two Nobel prizes and provided fertile
ground for innovating synchrotron techniques and making important
discoveries. SPEAR3 is a complete rebuild and upgrade of the
SPEAR2 ring, which was the original ring adapted for improved
performance in synchrotron radiation research.
Lines
extend from the ring to carry synchrotron radiation to experimental
stations. The new ring has the capacity to easily add eight
to 10 more beam lines, with associated experimental stations,
beyond the existing 11 beam lines. A $14.2 million gift from
the Gordon and Betty Moore Foundation to the California Institute
of Technology, announced Jan. 28, will allow scientists at
Caltech and Stanford to collaborate on the building of a designated
beam line at SPEAR3 for structural molecular biology research.
The exceptional quality and brightness of SPEAR3`s x-ray light
is perfectly suited to studying complicated biological systems.
The
first electron beams circulated in the new SPEAR3 ring in
mid-December 2003, and the first experiments are scheduled
to begin in March.
``SPEAR3
is a remarkable resource that will enable state-of-the-art
science in numerous fields,`` said SSRL Director and Stanford
Professor Keith Hodgson. ``The $58 million project was completed
on time and on budget. I thank the people whose extraordinary
teamwork made the project successful. In a remarkable accomplishment,
the old accelerator was dismantled, a new tunnel floor poured,
SPEAR3 installed and commissioned, and users back online -
all within a mere 11 months.``

MOLECULAR
FOUNDRY GROUNDBREAKING MARKS BERKELEY LAB'S LEAP INTO THE
NANOREVOLUTION
BERKELEY,
CA , USA. The term “Molecular Foundry” suggests a place where
objects are forged and new materials are molded. Like
the foundries of the industrial revolution, this
new concept, on a nanoscale, promises to revolutionize
the way the world works. It begins at the Department of
Energy’s Lawrence Berkeley National Laboratory – ceremonially,
on Friday, Jan. 30).
That’s
when ground was turned for the official beginning of construction
on a six-story, $85 million, 94,500-square-foot
research building that will be one of the centerpieces
of the DOE’s Nanoscale Research Program. Berkeley
Lab’s Molecular Foundry is one of five DOE research centers
to be constructed over the next few years.
“This
facility will assist scientists in reaching new frontiers
in the study of nanoscale research and its practical
application,” Secretary of Energy Spencer Abraham
said. “It represents a beginning of a revolution
in
science, opening up a broad array of innovation in materials
science, biology, medicine, technologies for environmental
research and national security.
“Berkeley
is blessed with tremendous resources, such as the national
supercomputing center (NERSC), the Advanced Light
Source, and the National Center for Electron Microscopy,”
he added. “All will be
instrumental
in the revolution in science offered by the Molecular Foundry.”
“Nanoscale
research will, in many respects, represent the new building
blocks for new technologies and applications across
the science and industry spectrum,” said Berkeley
Lab Director Charles Shank.
“Understanding
the properties of materials on the tiniest scale will
have an impact on everything, from medicine to manufacturing.”
Nanoscale
research enables scientists literally to build novel
structures atom by atom. The fundamental properties
of materials and systems are established at the
nanoscale. Nanomaterials,
typically on
the
scale of billionths of a meter, or 75,000 times smaller than
the width of a human hair, offer different chemical
and physical properties than the same materials
in bulk form, and have the potential to form the
basis
for new technologies. This especially includes the realm of
molecular biology.
Berkeley
Lab’s Molecular Foundry – actually the research building around
which Foundry programs will be developed – will
include six facilities available to users from
around the world. These include labs and experts devoted
to inorganic nanostructures; nanofabrication; organic,
polymer/biopolymer synthesis; biological nanostructures;
imaging and manipulation; and theory. Its focus
will be on the design, synthesis and characterization
of both “soft” (biological and polymer) and “hard” (inorganic
and microfabricated) substances and the integration of these
into complex assemblies.
The
SmithGroup of San Francisco designed the structure, which
will follow the contours of a hillside site between
a materials research building and the microscopy
center. Construction will be coordinated by
Rudolph
and Sletten, Inc. of Foster City. When completed in 2006,
the Foundry building will house more than 200
scientists and support staff, using state-of-the-art
instrumentation for imaging and manipulation.
Berkeley
Lab’s facility is one of five in the DOE’s proposed Nanoscience
Research Program; others will be developed at
Oak Ridge National Laboratory, Brookhaven National
Laboratory, Argonne National Laboratory
and
Sandia National Laboratories/Los Alamos National Laboratory.
The
possibilities to grow out of this and other initiatives dedicated
to the field of nanoscience are virtually limitless.
Some potential outcomes that have been suggested
include:
*
Carbon nanotubes -- sheets of graphite rolled into
extremely narrow tubes a few nanometers in diameter–
could be the possible building blocks of future
electronic devices.
*
Nanotechnology may one day enable the detection of
disease on the cellular level and the targeting
of treatment only to tissues where it is needed
in a patient’s body, potentially alleviating many unpleasant
and
sometimes harmful side effects.
*
Nanomanufacturing of parts and materials “from the
bottom up”—by assembling them on an atom-by-atom
basis—may one day be used to reduce waste and
pollution in the manufacturing process.
*
Nanosensors already are being developed to allow fast,
reliable, real-time monitoring for everything
from chemical attack to environmental leaks.
*
Woven into a cable, carbon nanotubes could provide
electricity transmission lines with substantially
improved performance over current power lines.
*
Certain nanomaterials show promise for use in making
more efficient solar cells and the next-generation
catalysts and membranes that will be used in hydrogen-powered

FEDERAL
NANOTECH CONFUSION SPREADS TO CALIFORNIA MICHAEL
CRICHTON MISTAKEN FOR RICHARD FEYNMAN
A report
released on January 20, 2004 in Sacramento indicates that U.S.
federal confusion over nanotechnology's original goal has spread
to the state of California, where the concept originated. The
report, "Nanoscience
and Nanotechnology: Opportunities and Challenges in California,"was
released yesterday at a meeting of the state's Joint
Committee on "Preparing California for the 21st Century."
Christine
Peterson, president of the California-based Foresight
Institute, addressed the Committee meeting: "The original
goal for nanotechnology -- systems of molecular machines,
building cleanly with atom-by-atom precision, as described
by Nobel physicist Richard Feynman -- is entirely absent from
the report. His name does not even appear.Instead, the concept
of molecular machines appears only in the form of 'plagues
of self-replicating nanobots,' as in Michael Crichton's thriller
Prey. The environmental benefits of molecular manufacturing
may be needlessly delayed by this confusion." Foresight
is the leading public interest group in nanotechnology.
Ray
Kurzweil, a National Medal of Technology winner who serves
on Foresight's Board of Advisors, commented: "While the
report has its visionary elements -- such as projecting 'intracellular
intelligent machines' within 15 years -- the omission of molecular
machine systems is extremely disappointing and, if not corrected,
may contribute to the state losing its natural lead in this
area."
Prof.
Ralph Merkle, a winner of the Foresight Institute Feynman
Prize in Nanotechnology and current chair of the Prize Committee,
stated, "This confusion was distressing enough when it
first appeared in Washington, but it is far more so in California,
where Feynman set the goal in 1959 at Caltech. It's true that
Caltech and Hollywood - where Michael Crichton thriller films
are made -- are not far apart geographically, but Californians
should know the difference."
Building
with atomic precision using molecular machine systems, also
known as molecular manufacturing, is seen as a key technology
for the environment, medicine, and defense. "This proposed
technology -- the 'nanofactory' - is our best hope for ending
chemical pollution as we know it today," said Peterson.
"California's strengths in design, systems engineering,
and software -- combined with its strong interest
in
restoring the natural environment -- give it an edge in this
area. The state's proposed Nanotechnology Research and Workforce
Advisory Council should include molecular manufacturing as
a major focus." ...read

A Tale of Two Nanotechs
It's the best of times for nanotechnology. Or is
it the worst of times? There's evidence in both directions.
On the upside, nanotechnology
is becoming real, with increasing numbers
of applications and breakthroughs. Even a dedicated observer
of the field (like, er, me) can't keep up with all the new
research and applications. And while we're a long way from
Drexlerian nanobots, we're a long way beyond mere gimmicks
like stain-resistant nano-pants, too….read
