Newswise — Using a water droplet 1 trillion times smaller than a liter of club soda as a sort of nanoscale test tube, a University of Washington scientist is conducting chemical analysis and experimentation at unprecedented tiny scales.

The method captures a single cell, or even a small subcellular structure called an organelle, within a droplet. It then employs a powerful laser microscope to study the contents and examine chemical processes, and a laser beam is used to manipulate the cell or even just a few molecules, combining them with other molecules to form new substances.

This nanoscale "laboratory" is so minuscule that it covers just 1 percent of the width of a human hair, said Daniel Chiu, a UW associate chemistry professor who is developing the unique method.

One of the great challenges in the field of nanotechnology is optical imaging-specifically, how to design a microscope that produces high-resolution images of the nano-sized objects that researchers are trying to study. For example, a typical DNA molecule is only about three nanometers wide-so tiny that the contours of its surface are obscured by light waves, which are hundreds of nanometers long.

Now, researchers from Stanford University have greatly improved the optical mismatch between nanoscale objects and light by creating the ``bowtie nanoantenna,`` a device 400 times smaller than the width of a human hair that can compress ordinary light waves into an intense optical spot only 20 nanometers wide. These miniature spotlights may one day allow researchers to produce the first detailed images of proteins, DNA molecules and synthetic nano-objects, such carbon nanotube bundles.

``One of our goals is to build a microscope with bowtie antennas that we can scan over a single molecule,`` says W.E. Moerner, the Harry S. Mosher Professor of Chemistry at Stanford...read the wave

Researchers have developed a human nephron filter (HNF) that would eventually make possible a continuously functioning, wearable or implantable artificial kidney. This study is published in the latest issue of Hemodialysis International.

The HNF is the first application in developing a renal replacement therapy (RRT) to potentially eliminate the need for dialysis or kidney transplantation in end-stage renal disease patients. The HNF utilizes a unique membrane system created through applied nanotechnology. In the ideal RRT device, this technology would be used to mimic the function of natural kidneys, continuously operating, and based on individual patient needs.

No dialysis solution would be used in the device. Operating 12 hours a day, seven days a week, the filtration rate of the HNF is double that of conventional hemodialysis administered three times a week.

“The HNF system, by eliminating dialysate and utilizing a novel membrane system, represents a breakthrough in renal replacement therapy based on the functioning of native kidneys,” say researchers. “The enhanced solute removal and wearable design should substantially improve patient outcomes and quality of life.” ..read the wave

PROVIDENCE, R.I., /PRNewswire/ -- Solaris Nanosciences has demonstrated a completely rechargeable dye sensitized solar cell (DSSC or Graetzel Cell) creating the lowest manufacturing cost, long-life photovoltaic system in the world. DSSCs which are based on low cost materials and simple construction, have to date suffered from limited operating lifetimes due to the degradation of the sensitizer dyes.

Solaris' nontoxic chemical process allows the degraded dye in already installed DSSCs to be removed and replaced with new dye, restoring the performance of the original solar cell. "This low cost process, which can be performed by the existing base of heating and air conditioning businesses, requires less than thirty minutes and takes the operating life of these photovoltaics (PV) beyond that of silicon to over 30 years," said Nabil M. Lawandy, CEO of Solaris Nanosciences. Lawandy also stated, "Not only can we replace the original dye, but we have shown that newer, more efficient dyes, resulting from ongoing efforts worldwide, can be used in recharging. This effectively allows for efficiency upgrades over the life of the installed system." ...read the wave

Nanocyl , one of the world's main producers of nanotubes, participates in the Nanomed project. Nanocyl participates with other key industry and university partners in this European research project. The project proposal entitled “NANOMED: Development of a carbon nanotube actuator for use in medical technology" was submitted within the framework of SME measures.

Medical technology, with annual growth rates of more than 10 percent, is one of the strongest growing sectors. On the European market, the annual turnover has already reached 80 billion euro. Considering the increasing life expectancy in Europe, it can be assumed that the need of medical technological devices and aids such as prostheses of all kinds will become even larger.

Already now some gaps in the market are evident as can be shown with the example of leg amputations: In Europe, annually approximately 47 000 leg amputations are carried out. However, only approximately 50% of the patients can be supplied with a prosthetic leg, as most of the patients are too weak to attach the prostheses and use them appropriately...read the wave

Blacksburg, VA --- There is a lot of excitement about incorporating nano particles into polymers because of the ability to improve various properties with only a small percent of the particles. "You can improve the barrier to gases, such as hydrogen, carbon dioxide, and oxygen. You can increase material strength with little increase in weight," said Don Baird, professor of chemical engineering at Virginia Tech.

But there are problems. "While 1 percent by weight of nano particles will change a material's properties dramatically, 2 or 3 percent provides hardly any additional enhancement," he said. "The particles just clump together, and thereby reduce the advantages associated with the surface area of single particles."

Another problem is that the incorporation of nano particles changes a polymer's flow properties leading to potential processing problems...read the wave

A key technological breakthrough led by the University of Edinburgh suggests that a futuristic world where people can move objects about “remotely” with laser pointers could be closer than we think. Chemists working on the nanoscale (80,000 times smaller than a hair's breadth) have managed to move a tiny droplet of liquid across a surface - and even up a slope - by transporting it along a layer of light-sensitive molecules.

Scientists at Edinburgh, Groningen and Bologna are the first to manipulate tiny nanoscale machines (two millionths of a millimetre high) so that they can move an object that is visible to the naked eye. The team has shifted microlitre drops of diiodomethane not just across a flat surface, but also up a one millimetre, 12 degree slope against the force of gravity. It may be the tiniest of movements, but, in the emerging discipline of nanotechnology, it represents a giant technological leap forward...read the wave

Automobile bumpers that deform and recover rather than crack and splinter, computer cases that withstand the occasional rough encounter, and resilient coatings that can withstand the ravages of the sun, may all be possible if tiny functionalized rubbery particles are imbedded in their plastic matrices, according to Penn State materials scientists.

"Plastics such as polypropylene, nylon, polycarbonate, epoxy resins and other compounds are brittle and fracture easily," says Dr. T.C. Chung, professor of materials science and engineering. "Usually, manufacturers take rubbery compounds and just mix them with the plastic, but there are many issues with this approach."

The problems include difficulty in controlling the mixing of the two components and adhesion between the plastic and rubber. Chung, and Dr. Usama F.

Newswise — Foggy windows and lenses are a nuisance, and in the case of automobile windows, can pose a driving hazard. Now, a group of scientists at the Massachusetts Institute of Technology (MIT) may have found a permanent solution to the problem. The team has developed a unique polymer coating — made of silica nanoparticles — that they say can create surfaces that never fog.

The transparent coating can be applied to eyeglasses, camera lenses, ski goggles … even bathroom mirrors, they say. The new coating was described today at the 230th national meeting of the American Chemical Society, the world's largest scientific society.

Researchers have been developing anti-fog technology for years, but each approach has its drawbacks. Some stores carry special anti-fog sprays that help reduce fogging on the inside of car windows, but the sprays must be constantly reapplied to remain effective. Glass containing titanium dioxide also shows promise for reduced fogging, but the method only works in the presence of ultraviolet (UV) light, researchers say...read the wave

Upton, NY, At the U.S. Department of Energy's Brookhaven National Laboratory, scientists have developed a new chemical "writing" technique that can create lines of "ink" only a few tens of nanometers, or billionths of a meter, in width.

Cai and his colleagues call the technique "Electro Pen Nanolithography" (EPN). They sweep a very thin metal tip across a film of organic molecules. The tip carries an electric voltage, which causes the region under it to "oxidize," or undergo a reaction that changes the chemical makeup of the film. In a single sweep of the pen, organic "ink" molecules are transferred from the tip to the oxidized regions, creating an extremely thin line...read the wave

Newswise — DNA isn't just for storing genetic codes any more. Since DNA can polymerize -- linking many molecules together into larger structures -- scientists have been using it as a nanoscale building material, constructing geometric shapes and even working mechanical devices.

Now Cornell University researchers have made DNA buckyballs -- tiny geodesic spheres that could be used for drug delivery and as containers for chemical reactions.

The term "buckyballs" has been used up to now for tiny spherical assemblies of carbon atoms known as Buckminsterfullerenes or just fullerenes. Under the right conditions, carbon atoms can link up into hexagons and pentagons, which in turn assemble into spherical shapes (technically truncated icosahedrons) resembling the geodesic domes designed by the architect-engineer Buckminster Fuller. Instead of carbon, the Cornell researchers are making buckyballs out of a specially prepared, branched DNA-polystyrene hybrid. The hybrid molecules spontaneously self-assemble into hollow balls about 400 nanometers (nm) in diameter. The DNA/polystyrene "rods" forming the structure are each about 15 nm long. (While still on the nanoscale, the DNA spheres are much larger than carbon buckyballs, which are typically around 7 nm in diameter.)...read the wave

Newswise — With an advanced imaging technique and a savvy strategy, researchers at Cornell University's Laboratory of Atomic and Solid State Physics (LAASP) have shown how adding charge-carrying atoms like oxygen to a superconductor can increase the material's ability to conduct electricity overall and -- paradoxically -- to decrease it in localized spots.

The discovery, published in the Aug. 12 issue of Science , could lead to the eventual development of more effective superconductors.

The scientists, led by Cornell professor of physics J.C. Séamus Davis, used a specialized scanning tunneling microscope (STM) in the basement of Cornell's Clark Hall for the research. They identified for the first time the locations of individual oxygen atoms within a particular superconductor's molecular structure and used that information to examine how the atoms affect current flow in their immediate vicinity. It's a small but vital step, they say, toward understanding how superconductors work.

AMES, Iowa – A genius well ahead of his time, Leonardo Da Vinci continues to inspire even 500 years after his remarkable life. His works are central to the best selling mystery novel The Da Vinci Code and its upcoming film adaptation, and his theories on friction are helping a group of scientists from the U.S. Department of Energy's Ames Laboratory and Lawrence Berkeley National Laboratory unlock the mystery of friction at the molecular level.

In a nutshell, Da Vinci proposed that if two contacting surfaces are geometrically similar, – commensurable – they will have a much higher coefficient of friction than two geometrically dissimilar surfaces, due to the fact that the similar surfaces have a tendency to interlock. To test this theory at the molecular level, the research team looked at a quasicrystalline material that exhibits both periodic and aperiodic configurations in its crystal structure. What they found, in results to be published in the August 26 issue of the journal Science, was that friction along the periodic surface was about eight times greater than the friction along the aperiodic axis...read the wave
