Nanogold does not glitter, but its future looks bright
If gold is created in small enough chunks, it turns red, blue, yellow and other colors, says Chris Kiely, who directs the new Nanocharacterization Laboratory in Lehigh's Center for Advanced Materials and Nanotechnology. Kiely, a professor of materials science and engineering, explores the properties of "nanogold," or gold particles so tiny - containing only hundreds or even tens of atoms - that they must be measured in nanometers. As is true with other materials, gold in "nano" form exhibits different properties from bulk gold.
