Abstract

We present the design of a microfluidic device and an electric circuit capable of combining both conventional and traveling-wave dielectrophoresis in a single microchip for the consecutive manipulation and separation of suspended particles according to their electrical properties. The high-gradient ac electric field is generated using an electrical power supply producing a phase-quadrature sinusoidal signal with the amplitude of up to 200 V (peak-to-peak) at the frequency of up to 250 kHz. We describe the operating principle of the device along with results of our preliminary experiments on suspensions of 4 - μm diameter polystyrene particles dispersed in deionized water.
