Abstract

The development of an electric field cell lysis device for microfluidic applications will be presented. Detailed modeling of the electrode configuration for the optimization of the electric field has been performed. Device design and fabrication has been accomplished using traditional integrated circuit (IC) manufacturing techniques. As a result, murine lymphocytes have been lysed using several electrode configurations. The requisite electric field strength and pulse parameters for cell lysis were determined. The non-specific adsorption of the released DNA to the materials used in the fabrication of the device was observed. Surface passivation of the fabrication materials was effected through the use of silanization compounds.
