Scientists are brining together a number of different disciplines as they explore nanotechnology. Sound is being included in many ways. Carbon nanotubes have been used to create a radio and music has been used to grow nanowires.

Wires

After testing Deep Purple's 'Smoke on the Water', Chopin's Nocturne Opus 9 no. 1', Josh Abraham's 'Addicted to Bass', Rammstein's 'Das Model', and Abba's 'Dancing Queen', David Parlevliet found that music can be used to grow nanowires but they will be kinky.

These days (early 2008), scientists want to grow straight nanowires and one of the popular methods is to "[blast] a voltage through silane gas to produce a plasma that pulses on and off 1000 times a second. Over time the process enables molecules to from the gas to deposit on a glass slide in the form of a mesh of crystalline silicon nanowires."  (Daily India)

Parlevliet, a PhD student at Murdoch University in Perth, Australia, plugged in a music player instead of a pulse generator usually used for this purpose and observed the results. While there are no current applications for kinky nanowires, the Deep Purple music created the densest mesh. Rammstein's music grew nanowires the least successfully. In his presentation to the Australian Research Council Nanotechnology Network Symposium in March 2008, Parlevliet concluded that music could become more important for growing nanowires if applications can be found for the kinky ones.

Radio

Researchers have created  a carbon tube radio which includes all the major components of an antenna, tuner, amplifier,  and demodulator. You can hear the radio play Layla,  Good Vibrations, Largo, and the Star Wars theme here. The radio is made from a single carbon nanotube, an entity smaller than a human hair. Future applications could include radio-controlled medical devices that can be transported through human bloodstreams or for smaller cell phones, according to the researchers of the Zettl Research Group, Condensed Matter Physics, Dept. of Physics, University of California at Berkeley.
