Researchers from Northwestern University have demonstrated the ability of a third-generation nanofountain probe to directly deposit gold nanoparticles, 15 nanometers in diameter, onto silicon substrates. The direct-write method of deposition provides better control over resultant patterns and simplifies the process of fabricating functional structures, as compared to conventional photolithographic or microstamping techniques.

If you have ever marveled over the orderly process by which cars, buses and other modes of transportation are directed toward their destinations in a big city, you'll really appreciate the work of one Florida State University chemist.

Devices made from plastic semiconductors, like solar cells and light-emitting diodes, could be improved based on information gained using a new nanoparticle technique developed at the University of Texas at Austin.

When it comes to searching out cancer cells, gold may turn out to be a precious metal. Purdue University researchers have created gold nanoparticles capable of identifying marker proteins making the tiny particles a potential tool to better diagnose and treat breast cancer.

Physicists at Georgia Tech have discovered a phenomenon which allows measurement of the mechanical motion of nanostructures by using the AC Josephson effect. The findings may be used to identify and characterize structural and mechanical properties of nanoparticles, including materials of biological interest.
