摘要
Building on the ability to exert torques in optical tweezers, optically-driven rotating micromachines have reached the verge of practical application. Prototype devices have been made, and useful applications are being sought. We outline some,eneral principles that can be applied to the design of optically-rotated devices, and describe a method for ricorous computational modelling that is well-suited to the optimization and engineering of such micromachines. Finally, we describe a method for rapid microfabrication of prototypes for testing, and some results of such tests.
