Fabrication of Microelectrodes on Polyester Membranes for Dielectrophoretic Cell Capture



Conni Hanke, Petra S. Dittrich, Darwin Reyes-Hernandez


We present a new system for cell capturing on permeable polyester (PET) membranes using dielectrophoretic forces. For the first time gold microelectrodes were fabricated on PET membranes using conventional photolithographic techniques. Their characterization revealed no physical differences before and after processing. Dielectrophoretic cell trapping was successfully carried out within this microfluidic system and cells remained viable at least a day after capturing.
