Abstract

This paper reports a hybrid electrokinetic processor that combines electrophoresis (EP), dielectrophoresis (DEP) and AC electrothermal flow (ACEF) for isolating exfoliated cancer cells (ECCs) and circulating tumor cells (CTCs) in physiological samples. While most electrokinetic techniques only function in low-conductivity buffers, hybrid electrokinetics enables effective operation in high-conductivity physiological fluids (∼ 1 S/m) such as blood, buffy coat and urine. Using a 3-electrode configuration with optimized AC voltage, frequency and DC offset, we demonstrate that breast cancer cells can be isolated in buffy coats and biological fluids in 10 sec.
