Abstract：

The invention relates to a method for micro-fluid movement controlling optically. Specifically, the invention discloses a method and device for micro-fluid movement controlling optically and a micro-tube actuator. According to the method, the micro-tube actuator is prepared by using a photoinduced deformation intelligent polymer material, and the micro-tube actuator can be changed from a symmetrical cylindrical shape into an asymmetric cone under light stimulation and induced to generate capillary force to drive a micro-liquid to move. According to the method, micro-liquids of all kinds of polarities and compositions can be driven, micro-liquid climbing can also be driven, and the fluid can even be driven to produce a three-dimensional trajectory; and the method has the considerable potential application value in the fields of controllable micro-fluid transmission, micro-reaction systems, micro-mechanical systems, chip laboratories and the like.
