Design and evaluation of electrode for dielectrophoretic characterization of blood cells

Abstract

Dielectrophoresis can be used to determine the dielectric properties of biological cells. In this paper, we present an electrode design for characterization of blood cells by measuring negative dielectrophoretic force. The negative dielectrophoretic force acting on glass beads in distilled water was measured by inclined gravity to evaluate the effectiveness of the designed electrode. The designed electrode generated the negative DEP force ranging from 0.21 pN to 1.89 pN with 20 Vpp, 1 MHz. The distribution of the dielectrophoretic force was consistent with the calculated results.
