Design and analysis of microfluidic channel with W-shaped electrodes for separation of bio-particles using dielectrophoresis technique

A unique microfluidic device with W-shaped electrodes is designed to separate the micro-bio-particles. The microfluidic device efficiently separates the red blood cells (RBCs) and platelets using the dielectrophoresis technique. The separation process has been analysed by using COMSOL Multiphysics software and found that the electrode with the minimum gap of 25 µm acquired optimum results at an applied voltage of 8 V. The proposed device gave a high separation efficiency of 89.5% and a separation purity of 99.63%. The enhanced microfluidic device gave better results compared to other recent works and is exceptionally suitable for separation of micro-bio-particles.
