Continuous Flow Microfluidic Channel Design for Blood Plasma Separation
Various clinical blood diagnostics tests are performed on plasma, necessitating an efficient microfluidic device for blood plasma separation. Microfluidics devices are being explored for such applications and many of them are successfully deployed. This work demonstrates a passive microchannel design for continuous flow blood-plasma separation. The design uses the multistage bifurcations and constrictions to separate blood plasma. Simulation results show that the more plasma yield is obtained by reducing the angle of bifurcation, decreasing the constriction width and by increasing the bifurcating stages. The simulation shows that yield obtained after optimizing the geometry is 97.03%.
