WITHDRAWN: Design and analysis of MEMS model to separate white blood cells from human blood

Abstract

In this paper, a microfluidic channel is designed and modelled using Comsol Multiphysics to differentiate blood cells into platelets, white blood cells (WBC), and red blood cells (RBC). Finally, white blood cells are separated. The main reason for separating white blood cells is these cells should be injected into a person's blood separately who's WBC count is less. Blood transfusion is very important treatment that replaces blood cells. Separation technique uses dielectrophoretic force on the particles so that the particles flows through a micro-fluid channel are separated. The flow of cells through a micro channel is modeled by giving an alternate voltage of 5 V for the separation region. These particles are demonstrated dielectrophoretic behavior in the presence of electric fields. Under the power of Dielectro-phorosis (DEP) energy, we observed the flow of separating platelets, WBCs, and RBCs. In this study, we proposed a two-stage microfluidic device. In the first stage we separated platelets for the blood as there are two outlets, from one outlet platelets are separated and through another outlet a combination of WBCs and RBCs are flown. In the second stage the WBCs are separated from other blood cells.
