抄録

A particle separation technique in a sub-mili channel has been developed by utilizing the acoustic radiation and electrostatic forces, which will be applicable to microfluidic devices. When the acoustic radiation force was applied by an ultrasound transducer, large and small particles were trapped at nodal positions in the standing field, which was equal to half of the wavelength in the transverse direction. On simultaneous application of electric field to the channel, both forces acted on particles. The relationship between the acoustic radiation and electrostatic force acting on particles was investigated in order to separate particles in the flow field.
