In his laboratory at Harvard University, chemist Charles M. Lieber puts a drop of clear solution onto a tiny silicon wafer. It looks like any old liquid, but it isn't. Suspended in the fluid are millions of wires, tens of thousands of times thinner than a human hair. These wires could become the building blocks of smaller, cheaper, and faster electronics.

Using these nanowires, Lieber and other physicists, chemists, and engineers are t
