Charged particle/cell manipulation in spiral microchannels with concentric electrodes

In this study, a solution has been proposed by investigating the manipulation and separation of charged particles in spiral microchannels and concentric electrodes. Proposed structure has been fabricated by using MEMS technology and characteristics of electrophoretic force has been demonstrated successfully. Negative charged particles could be manipulated at different speeds and in opposite directions depending on the amplitude and the polarity of the applied electric field. It has been planned that results of this study will be used in the differentiation of charged cells.
