Authors have been developed a novel noncontact stirring method of slight amount DNA contents droplet. We have confirmed that the stir of the μL order droplet has not progressed easily by the conventional shaking machine, and short processing time of DNA hybridization is difficult. Therefore, we tried a new method. This droplet shows active motion between electrodes under high voltage AC. electric field. We have proposed new stirring method for slight amount DNA contents droplet. Then we have obtained good result at the stir time of 1/3 of the method.
