Abstract
Provided is a device and method of manipulating particles. The device includes: a channel for accommodating an electrolyte solution including particles to be manipulated; an anode and cathode for imposing a direct current (DC) electric field on the channel; metal strip(s) attached to an inner wall of the channel and resulting in induced-charge electroosmosis near a surface of the channel; a DC power supply unit for supplying a DC voltage to the anode and the cathode of the channel; control electrodes on both sides of the metal strip(s) to locally tune the induced-charge electroosmosis on the metal strip(s) regardless of the global electric field across the channel; and a DC power supply unit for supplying a DC voltage to the control electrodes.
