Glass slivers conduct current at the nanoscale
U. MICHIGAN (US)—On a very small scale, physics can get a little peculiar. Biomedical engineers have discovered such a nanoscale phenomenon and think it could lead to faster, less expensive portable diagnostic devices. (more…)

“Cell listeners” shine light on nanoscale function
U. ILLINOIS (US)—One way to understand biological structures and mechanisms, according to researcher Gabriel Popescu, is to “listen to them” through the use of new optical imaging methods that measure cellular motion at the nanoscale. (more…)

Scientists film photons with electrons
CALTECH (US)—Recently invented techniques—that allow the real-time, real-space visualization of fleeting changes in the structure of nanoscale matter—have been used to image the evanescent electrical fields produced by the interaction of electrons and photons, and to track changes in atomic-scale structures. (more…)

Patchy particles show promise for drug delivery
U. PENN (US)—A team of physicists, chemists, and engineers has demonstrated a novel method for the controlled formation of patchy particles, using charged, self-assembling molecules. The particles may one day serve as drug-delivery vehicles and perhaps be used in small batteries that store and release charge. (more…)

Candid camera at the nanoscale
“This is engineering at the ultimate atomistic limit,” says V. Ara Apkarian, who is leading a team attempting to record the first time-lapse images of single molecules. “There’s no question the tools that enable the observation and manipulation of one molecule at a time will be the pillars on which the field of nanotechnology will be built.”

High-speed images reveal essence of liquid
Simulation of a granular stream in free fall, breaking into particle clusters like droplets in a stream of water falling from a faucet. As in ordinary liquids, weak attractive forces drive the clustering, but result here in a novel, ultra-low surface tension fluid. (Credit: University of Chicago)

Staging a nanoscale disappearing act
CORNELL—Researchers have developed a device that can make it seem that a bump in a carpet—or, indeed, any flat surface—isn’t there. So far the illusion works only at the nanoscale, but the researchers from Cornell University suggest that the basic principle might eventually be scaled up for military and communications applications, or perhaps used in reverse to concentrate solar energy.
