5. In 1988,Pmfessor Richard Muller and c0eagues made the first 0peratlng micromotor,which as 100 microns across,0r about the thickness of a human hair. In 2003,Zettls group created the first nanoscale motor. In 2006,they buih a nanoconveyor,which moves tiny panicles a10ng Iike carsin a factory。
6.Nanotechnology engineers try to mimic nature,building things atom-bv-atom-Among other things,nanomotors could be used in optical circuits to redirect light,a process called optical switching。Futurists envision a day when nanomachines,powered by nanomotors,travel inside yur body to find disease and repair damaged cells.
