Engineers from Austin University of Texas found a way to change the mechanical movement of nanotores with several modes with light.
Variating the intensity and frequency of light radiation, the researchers were able to change the behavior of nanoche. The principle of operation of the simplest tiny electric motors externally resembles a fan, but they function as transistors, responding to external impact. The tests were carried out with various metals and semiconductors, observing their mechanical movement during the irradiation of nanotores in aqueous solution.
Scientists have discovered that depending on the intensity of the incoming light (from the level of the projector to the laser), the silicon device can be caused in motion, stop or force them to rotate in the opposite direction. This effect was observed for the first time. Due to the possibility of converting energy in motion, the nanoomotors can be used when creating controlled nanoelectromechanical devices and robotics for the delivery of drugs, optical recognition, communications, interactions with molecules, separation of individual nanoparticles and other purposes.
Australian researchers also discovered the amazing properties of the simplest nanostructures. They created
