Recent trends in dielectrophoresis

Abstract

The paper presents the recent development of one important BioMEMS application: delectrophoresis. A classification of dielectrophoretic devices, recent work in the field as well as theoretical consideration and numerical simulation will be presented in the first part of the paper. The second part of the paper presents some dielectrophoretic chip developed by the authors. Different structures of DEP devices such as DEP devices with 3D electrodes, DEP chip with asymmetric electrodes as well as an isolating DEP 3D filter are presented. The main biological applications of these microfluidic devices are: cell trapping and separation of two cellular populations. Some field-flow separation methods performed on the above mentioned chips are described.
