Molecular guitar

Dustin W. Carr from Professor Harold G. Craighead's group developed the molecular guitar (or nano-guitar ) at Cornell Nanofabrication Faculty in 1997 as a humorous and successful idea for presenting nanotechnology . Whether the molecular guitar can be classified as an actual guitar is controversial. The length of the molecular guitar is 10 micrometers , which is one twentieth the thickness of a human hair. The six strings are each 50 nanometers thick. The overall guitar size corresponds to that of an average erythrocyte . The molecular guitar is made of crystalline silicon , was shaped by a laser using electron beam lithography and can be played using tiny lasers in an electron microscope. The pitch of the guitar is 17 octaves higher than classical guitars , which is why the guitar cannot be perceived by the human ear even with extreme amplification.
