一种可对微小物体实施旋转控制的新式光钳最近由美国圣安德鲁大学公布于世。该方法不仅应用在生物学和化学领域，而且还可应用于微机械的能量传输方面。光钳是近１０年间迅速发展的一项技术。它是利用聚焦的激光束移动微小物体，目前在遗传基因操作和体外受精等生物学领域已被 A new type of optical pliers capable of rotating control of tiny objects was recently published by the University of St Andrews. This method is not only used in the fields of biology and chemistry, but also applied to the energy transfer of micromechanics. Light pliers is a rapidly developing technology in the past 10 years. It uses the focused laser beam to move tiny objects and is currently used in biological fields such as gene manipulation and in vitro fertilization
