nano guitar

A guitar the size of five red blood cells has been constructed by a graduate student at Cornell University in Ithaca, N.Y. Lidija Sekaric built the tiny instrument using electron-beam lithography, a technique used to create microcircuits. The strings move well enough to play "Bugle Call." The sound is outside the range of human hearing but detectable to instruments. A university spokesman says that by playing a nanoguitar, physicists are demonstrating how such devices could substitute for electronic circuit components to make circuits smaller and cheaper.
