The behavior of fine particles under newly designed separation field by combining DC electric field with electromagnetic field of laser light and/or laser-induced temperature field, were examined in detail. By using combination of electrophoresis and laser photophoresis, it was revealed that micro-particles with different properties, such as particle size, zeta potential and light absorbing, can be separated in the reverse direction. It was found that efficient separation by designed combination field is available in particular for micro-particles with light absorption.

详细研究了直流电场与激光电磁场和激光诱导温度场相结合的新型分离场作用下细颗粒的行为。结果表明，采用电泳与激光电泳相结合的方法，可以将粒径、zeta电位、吸光度等性质不同的微粒反向分离。结果发现，通过设计的组合场的有效分离是可用的，特别是对于具有光吸收的微粒。
