Verification of Structural Parameters of DEP Cell Sorter for Higher Speed and Discrimination

Abstract

For clinical application of cell sorting method to regenerative medicine, micro fluidic cell sorter, based upon the DEP force principle and μTAS technology, was fabricated. For better sorting discrimination, 3-fold symmetry design was employed. The symmetric alignment of flow channel and electrodes enabled reduction of electrode gap to 1/3 of the conventional design. It suggests the enhancement of DEP force increase by an order, and higher discrimination accuracy.
