Nanosized light mill drives micro-sized disk
07/05/10 Berkeley Lab — Engineers at Lawrence Berkeley National Laboratory and the University of California Berkeley have created the first nanosized light mill motor whose rotational speed and direction can be controlled by tuning the frequency of the incident light waves. This new light mill opens the door to a broad range of valuable applications, including a new generation of nanoelectromechanical systems (NEMS), nanoscale solar light harvesters, and bots that can perform in vivo manipulations of DNA and other biological molecules.
