For the first time, scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory have shown how a powerful electron microscope can provide direct insight into the performance of any material by pinpointing specific atomic "neighborhoods." In particular, the scientists made molecular movies showing how the nanostructure of a semiconductor used in organic solar cells changed in response to a common processing additive known to enhance solar cell efficiency.

MIT engineers have shown that they can enhance the performance of drug-delivery nanoparticles by controlling a trait of chemical structures known as chirality—the "handedness" of the structure. The MIT team found that coating nanoparticles with the right-handed form of the amino acid cysteine helped the particles to avoid being destroyed by enzymes in the body. This finding could help researchers to design more effective carriers for drugs to treat cancer.

Researchers at the University of Washington have developed a method that could make reproducible manufacturing at the nanoscale possible. The team adapted a light-based technology used widely in biology—known as optical traps or optical tweezers—to build a novel nanowire heterostructure, which is a nanowire consisting of distinct sections comprised of different materials.

An international team of researchers has used nanoparticles to deliver a drug into specific compartments of nerve cells, dramatically increasing its ability to treat pain in mice and rats. The drug that the researchers encapsulated into nanoparticles is an FDA-approved drug used to prevent nausea and vomiting that had previously failed clinical trials as a pain medication.

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have devised a scheme for assembling light-absorbing molecules and water-splitting catalysts on a nanoparticle-coated electrode. The result is the production of hydrogen gas fuel via artificial photosynthesis—a lab-based mimic of the natural process aimed at generating clean energy from sunlight.
