我们展示了一种利用二极管激光棒在微流体系统中捕获、分类和操纵细胞和微米级颗粒的新技术。该方法克服了传统扫描激光陷阱的尺度限制，同时避免了全息光学陷阱方案固有的计算和光学复杂性。二极管激光棒使我们能够控制一个大的捕获区，1 μ m × 100 μ m，而不需要扫描或改变光束的相位。(C) 2004美国光学学会。
We demonstrate a new technique for trapping, sorting, and manipulating cells and micrometer-sized particles within microfluidic systems, using a diode laser bar. This approach overcomes the scaling limitations of conventional scanned laser traps, while avoiding the computational and optical complexity inherent to holographic optical trapping schemes. The diode laser bar enables us to control a large trapping zone, 1 mum by 100 mum, without the necessity of scanning or altering the phase of the beam. (C) 2004 Optical Society of America.
