| Research Abstract |
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.
