We report the method for control technique of nanoparticles. We demonstrate the use of alternating current inhomogeneous electric field generated by electrodes, for the control of nanoparticles. The electrodes are made of ITO on glass was fabricated by micro-electromechanical systems (MEMS) technology. In recent years, a study of handling aimed at analyzing living body nanoparticles such as DNA or the protein is performed flourishingly. In this study, we use the dielectrophoresis (DEP) that is one of the handling techniques. The dielectric migration used the interaction of an induced particle and the electric field in the inhomogeneous electric field. Unlike the electrophoresis, we are able to control a particle without the electric charge cells and microbes of the quantity of slight electric charge by low voltage. However, Brownian motion becomes dominant if particle diameter becomes small. So, we handle the nanoparticle by restraining the Brownian movement of the nanoparticle.
