Professor Weihua Li

This paper presents a numerical study of particle trapping using quadrupole microfludic dielectrophoretic device. By taking into account the dielectrophoreis, viscous drag, the trajectory of particles flowing through the quadrupole device was obtained. Simulation results show that the device is effective for negative trapping, where particles are effectively trapped at the device centre. The device geometry is optimized by maximizing the dielectrophoretic force.
