In a novel application of light torques, we manipulate and control the rotation of nanorods. We apply light torques to 250 nm diameter glass nanorods in a single-beam optical trap. Light-torque operated nanomotors whir at moderate speeds that depend on several factors, including the magnitude of the light torque, the viscosity of the surrounding medium, and the rotation rate of the electric field vector of the linearly polarized trapping light. Two new modes of behavior - rocking motion and saltatory motion -are also described and explained.
