label-free perfect separation of michigan cancer foundation-7 cells from white blood cells using both wall-induced lift and dielectrophoresis forces

A microchannel device was designed and utilized to separate michigan cancer foundation-7 cells from white blood cells using both wall-induced lift and di-electrophoresis forces. using comsol multiphysics simulator, the label-free separation process is performed based on the radius size of the particles. the best performance of the structure is obtained with the efficiency of 100% and 99% for cancer and white blood cells separation processes, respectively. for the proposed microfluidic structure, in addition to the highest available efficiency and high separation speed of 12 um/s, the low dc voltage of 6 v is applied, which causes negligible damage to the blood cells.
