In numerous of studies, dielectrophoresis (DEP) has proven that its high selectivity and versatility make it a promising separation technique in a variety of fields. So far, however, only a few processes in the bioanalytics have made it to commercial use. One of the main challenges is to achieve a technically relevant throughput while maintaining a high selectivity. In one recent publication we present a novel approach of a mesh-based DEP filter with ordered field disturbing structures that has a high potential for upscaling because low-cost and commercially available materials are used. Another recent approach from our lab presents and characterize a separator based on two inexpensive custom-designed printed circuit boards (80 × 120 mm board size).
