Optical trapping and transportation of microorganisms by the moving interference pattern was demonstrated with low-power (~50mW) HeNe-laser. Novel type of short-pulsed (ns) electrophoresis induced by photogalvanic effect is suggested and tested. We propose to use novel synergetic approach, based on synchronous application of optical trapping and pulsed electrical field for transportation and selective separation of solution components.
