Combined the dielectrophoresis(DEP)effect with the affinity capture of the biomolecule,the negative DEP force could overcome the non-specific adhesive forces without the recognition capability during the process of cell capture to decrease the adhesive number of the non-target cells and improve the captured purity.According to DEP principle,the cell-captured microfluidic chip with gear shaping electrode structure was designed and fabricated.The electrode width is10μm and the electrode spacing is 40μm.The AC...
