简介:Optofluidics是光学和microfluidics(薄片上的所谓的实验室)的集成。液体的使活动在那里是一种关键技术。在为控制microscale液体的许多方法,轻使活动特别地有趣。轻使活动提供一个新奇方法控制液体的流动为生物医学并且biotechnological应用,等等……设备的复杂性和费用可以被使用完全的光控制极大地有时减少并且可能比另外的方法在操作更灵活。然而,液体的轻使活动是象optofluidics一样的一块发芽的地。有大量工作做。这里,我们系统地基于下列点为液体的轻使活动描述四机制:optoelectrowetting,photothermal效果,放射压力,感光性的物质。
