ELECTRODELESS DIELECTROPHORESIS OF VIRUSES IN POLYMERIC MICRODEVICES

The electrodeless dielectrophoretic trapping and concentration of viruses was demonstrated. Dielectrophoresis is the motion of matter caused by polarization effects in a nonuniform electric field. Experiments were performed on a glass chip with insulating posts in order to study the dielectrophoretic behavior of the viruses and extend the application of insulative (electrodeless) Dielectrophoresis (iDEP) to polymeric microdevices. The ultimate goal of his research project is to create a highthroughput EDEP system using polymers as substrate. Only two electrodes were present in the system. In the presence of an applied DC electric field the viruses exhibited streaming and trapping dielectrophoresis.
