A particle separation technique without complex mechanical structure has been developed in a sub-mili channel. This is of importance to various operations in microfluidic devices. Size separation was demonstrated by utilizing acoustic radiation and electrostatic forces which acted simultaneously on the particles perpendicular to the flow direction in the sub-mili channel. By acoustic radiation forces an inhomogeneous distribution of particles was formed. By applying electrostatic forces the particles were moved parallel to electrodes without disrupting their size distribution. Therefore the local concentration of the particles can be controlled by the present technique.
