Theoretical and experimental study of the membrane pore effect on the amplitude-frequency dependence of polarizability of a cell

The amplitude-frequency dependence of the polarizability of erythrocytes, yeast cells, and latex particles in the range of 1–10 6 Hz was studied by the method of dielectrophoresis (DEP). Positive DEP of erythrocytes and yeast cells in a frequency range of 60–100 Hz was revealed. The positive DEP of cells in the given range is theoretically explained by appearance of a great number of transverse pores through the membrane and wall of the cell.
