``OPTICAL CATALYTIC NANOMOTORS''

D. Kagan, \textit{et.al, } 2009:'' a motion-based chemical sensing involving fuel-driven nanomotors is demonstrated. The new protocol relies on the use of an optical microscope for tracking charge in the speed of nanowire motors in the presence of target analyte''. Synthetic nanomotors are propelled by catalytic decomposition of .. they do not require external electric, magnetic or optical fields as energy..\textless pubs.acs.org/cen/science/83/i08/8308sci1.html\textgreater .
