在光扭矩的新颖应用中，我们操纵和控制纳米棒的旋转。我们对单光束光阱中直径 250 nm 的玻璃纳米棒施加光扭矩。光扭矩操作的纳米电机以中等速度旋转，该速度取决于几个因素，包括光扭矩的大小、周围介质的粘度以及线偏振捕获光的电场矢量的旋转速率。还描述和解释了两种新的行为模式——摇摆运动和跳跃运动。 (C) 2002 年美国光学学会。
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. (C) 2002 Optical Society of America.
