More Than One Nanostring To Their Bow: Scientists Moving Closer To 'Artificial Noses'

ScienceDaily (Apr. 29, 2009) — These days, chemical analysts are expected to track down even single molecules. To do this highly sensitive detective work, nano researchers have developed minute strings that resonate in characteristic fashion. If a molecule docks onto one of the strings, then it becomes heavier, and its oscillations become measurably slower. Until recently, however, such “nano-electromechanical systems”, or NEMS, have been short of practical applications.
