Nanoscale plasmonic motor

A nanoscale plasmonic motor (sometimes called a "light mill") is a type of nanomotor, converting light energy to rotational motion at nanoscale. It is constructed from pieces of gold sheet in a gammadion shape, embedded within layers of silica. When irradiated with light from a laser, the gold pieces rotate. The functioning is explained by the quantum concept of the plasmon. This type of nanomotor is much smaller than other types, and its operation can be controlled by varying the frequency of the incident light.
