FIG. 1.

20 μm pillar contactless dielectrophoresis device. (a) Top view photo and (b) exploded schematic of a cross section across a row of pillars with white space added to visually separate layers. The main channel is colored green and contains inlets for both cell suspension and DEP buffer. Electrode channels are colored purple, they are filled with 10 × PBS and connected to the high voltage generator. An electric field is applied across each chamber, perpendicular to the direction of fluid flow.
