利用三维双光子微细加工技术研制了一种光驱动的波瓣微泵。两个内置的转子，9微米的直径，是协同驱动的时分扫描的一个单一的激光束。结果表明，示踪粒子的移动，同时旋转的两个转子。示踪粒子的速度在0.2-0.7 μ m/s范围内与转子的转速成正比。流速估计为亚pL/min水平。这种超低流速将有助于微全分析系统的进一步集成和小型化。(c)2006年，美国物理学会。
An optically driven lobed micropump was developed using three-dimensional two-photon microfabrication. The two built-in rotors, 9 mu m in diameter, are cooperatively driven by means of time-divided scanning of a single laser beam. It was demonstrated that a tracer particle was moved by simultaneously rotating the two rotors. The velocity of the tracer particle was proportional to the rotation speed of the rotors in the range of 0.2-0.7 mu m/s. The flow rate was estimated to be sub-pL/min level. This ultralow flow rate will be useful for further integration and miniaturization of micro-total-analysis systems. (c) 2006 American Institute of Physics.
