Abstract：The paper introduced the recent development of optical tweezers array. The particle manipulation system could be set up based on several methods, such as acousto-optics deflectors (AOD), diffractive optical elements (DOE), spatial light modulators (SLM), interference technique, vertical cavity surface emitting laser (VCSEL), optical fibers and micro-lens arrays as well. The principle, specification and basic structure of each method were introduced and analyzed briefly. Taking the advantage of particle trapping, optical tweezers array was very useful for manipulation of micron size particles, such as cells. Combining with microfluidics and MEMs fabrication, optical tweezer array, the ultraminiature and portable particle sorting system, would be a good choice for space biological research.
