Manipulation of Biological Samples using Electric Field

The paper presents original contributions at manipulation of biological samples using electric field (dielectrophoresis). Design considerations, fabrication processes and experimental results of three original three dimensional (3D) dielectrophoretic (DEP) structures: DEP chip with 3D silicon electrodes, DEP chip with 3D electric field gradient and 3D filtering chip are analyzed. The paper presents also the experimental results of trapping yeast cells.
