A dragonfly as small as a dust mote, its four tiny wings beating like it had momentarily alit on a lily pad, and a highly sensitive microvalve were the big winners in this year's student design contest for extraordinarily tiny devices at Sandia National Laboratories.
Viruses that attack plants, insects, mammals and bacteria are proving effective platforms for delivering medicines and imaging chemicals to specific cells in the body, as building blocks for tiny battery electrodes and computer data storage devices, and other nanotechnologies.
For the first time, scientists at IBM Research have demonstrated that a relatively new memory technology, known as phase-change memory (PCM), can reliably store multiple data bits per cell over extended periods of time.
A team of engineers and scientists at the University of British Columbia has developed a device that can be implanted behind the eye for controlled and on-demand release of drugs to treat retinal damage caused by diabetes.
The Center of Innovation for Nanobiotechnology (COIN) and the Joint School of Nanoscience and Nanoengineering (JSNN) are proud to co-sponsor an informational seminar "Leveraging Supercomputing in Nano/NanoBio Research" on Wednesday July 20, 2011.
Researchers have observed that the light emitted by a single atom may exhibit much richer dynamics. Strongly interacting with light inside a cavity, the atom modifies the wave-like properties of the light field, reducing its amplitude or phase fluctuations below the level allowed for classical electromagnetic radiation. This is the very first observation of "squeezed" light produced by a single atom.
Based on DMI's successful work under a pair of Phase II Small Business Innovation Research Program contracts designed to develop nanoscale diagnostic technologies that facilitate whole health analysis in a single drop of blood, DMI's rHEALTH sensor has been identified by NASA as a viable approach for performing blood and urine analysis on the International Space Station.
IMRE's patented synthetic cell membranes can be made-to-order, are easier to maintain in a laboratory environment and do not require the lengthy preparation that comes with working on live cell membranes. The synthetic cell membranes mimic the natural functions of cell membranes, such as interacting with drug molecules and antibodies, which is crucial in the drug discovery process.
Whether packing oranges into a crate, fitting molecules into a human cell or getting data onto a compact disc, wasted space is usually not a good thing. Now, Princeton University chemist Salvatore Torquato and colleagues have solved a conundrum that has baffled mathematical minds since ancient times - how to fill three-dimensional space with multi-sided objects other than cubes without having any gaps.
