NEW
MATERIAL COULD BE USED
IN DRUG DELIVERY SYSTEM
|
|
University
of Toronto researchers have developed a
new class of hybrid materials that could
one day move drug delivery systems to the
molecular level.
The
paper published in the Nov. 26 issue of
Science outlines how a U of T research team
combined two classes of nanomaterials to
create an entirely new composite structure.
This new porous architecture may one day
act as a nanoscale sieve, enabling researchers
to release drug molecules in a slow and
controlled way. "We hope one day to
create a film of this material and spread
it on the skin," says the paper's senior
author University Professor Geoffrey Ozin
of the Department of Chemistry. "By
doing so, drugs can be diffused through
the skin, rather than injection, which would
guarantee a continuous flow of a drug molecule
at a tunable rate and concentration."...read

Astronaut's

ANN
ARBOR, Mich.---Our eyes may become more
than windows of the soul if a multidisciplinary
team of University of Michigan researchers
succeeds with a clever combination of nanoparticles
and ultrafast pulsed laser to see individual
cells as they zip past in the bloodstream.
The
U-M team of physicians, scientists and engineers
has $3 million from NASA to determine a
way of detecting radiation exposure on the
fly by looking for individual cells that
have been harmed. Now, such cell counting
is only achieved by drawing blood and using
an expensive machine called a cytometer,
operated by a skilled lab technician...read

On
August 4, 2004, Nanosys Inc. withdrew its
Initial Public Offering application. Nanosys
was widely viewed as the first start-up
focused exclusively on nanotechnology to
seek to go public. The offering was perceived
to be a litmus test for investor interest
in the field and many hoped it would clear
the way for more nanotech IPOs. Nanosys’
withdrawal, however, made financing prospects
for nanotech companies in both public and
private markets unclear. A scholarly analysis
of the outlook for future nanotech financing
activities is urgently needed and in this
article, R. Douglas Moffat and Ruben Serrato
explore current capital market conditions
for nanotech companies seeking funding. |

Improved
Molecular Switch
Could Serve as Sensor, Medical Tool
|
|
Newswise
— Improving significantly on an early prototype,
Johns Hopkins University researchers have
found a new way to join two unrelated proteins
to create a molecular switch, a nanoscale
“device” in which one biochemical partner
controls the activity of the other. Lab
experiments have demonstrated that the new
switch performs 10 times more effectively
than the early model and that its “on-off”
effect is repeatable.
The
new technique to produce the molecular switch
and related experimental results are reported
in the November issue of the journal Chemistry
& Biology. The paper builds on earlier
research, led by Marc Ostermeier, which
demonstrated that it was possible to create
a fused protein in which one component sends
instructions to the other. The second then
carries out the task...read

Revamped
CORDIS service on nanotechnology reflects
huge importance of the very small
|
|
CORDIS,
the Community Research and Development Information
Service, has launched a newly revamped information
service on 'nanotechnology', bringing together
news and information from diverse sources
on developments in technologies based on
nano-scale engineering.
Nanotechnology
applications include health care, information
and communication technologies, materials
sciences, manufacturing, instrumentation,
energy, security and space. Reflecting this
growing importance, the European Commission
held a public consultation on the future
of nanotechnology in Europe, following its
communication 'Towards a European strategy
for nanotechnology' in May 2004. An action
plan is in preparation, and initiatives
in this area have been coordinated via the
Irish and Dutch Presidencies, as well as
the NanoForum, an EU sponsored thematic
network for the business, scientific and
social communities....read

HILLSBORO,
Ore., PRNewswire-FirstCall/ -- FEI Company
(Nasdaq: FEIC) have announced that it has
been selected by the several laboratories
that have combined to form the TEAM project,
as the R&D partner for building the
highest resolution scanning - transmission
electron microscope ((S)TEM) in the world.
TEAM is a multi-million dollar microscopy
project funded by the U.S. Department of
Energy's (DOE) Office of Basic Energy Sciences.
The project calls for a new microscope that
will enable extraordinary new scientific
opportunities for direct observation and
analysis of individual nanostructures at
an unprecedented resolution of 0.5 Angstrom
-- approximately one-third the size of a
carbon atom -- a key dimension for atomic

to sell a nanotech golf ball that promises
to dramatically reduce hooks and slices

That
