Abstract

A microfluidic cell for the dielectrophoretic separation, accumulation, and/or lysis of polarizable bioparticles, including an interdigital electrode system composed of two electrode groups having interdigitated electrodes, and a micromixer having microchannels and microelevations. The interdigital electrode system and the micromixer are situated on the same side of the cell to improve the separation, accumulation, and/or lysis characteristics. Moreover, also described is a microfluidic system which includes such a microfluidic cell, and use thereof, and a method for separating, accumulating, and/or lysing polarizable bioparticles.
