Abstract

This short communication introduces a continuous-flow, dielectrophoresis-based lateral fluid flow fractionation microdevice for detection/isolation of circulating tumor cells in the presence of other haematological cells. The device utilizes two sets of planar interdigitated transducer electrodes micropatterned on top of a glass wafer using standard microfabrication techniques. A microchannel with a single inlet and two outlets, realized in polydimethylsiloxane, is bonded on the glass substrate. The two sets of electrodes slightly protrude into the microchannel. Both of the electrode sets are energized with signals at different frequencies and different operating voltages ensuring that the cancer cells experience positive dielectrophoretic force from one set of the electrodes and negative dielectrophoretic force from the other array. Normal cells experience unequal negative dielectrophoretic forces from opposing sets of electrodes. The resultant dielectrophoretic forces on cancer and normal cells push them to flow towards their designed outlets. Successful isolation of green fluorescent protein-labelled MDA-MB-231 breast cancer cells from regular blood cells, both suspended in a sucrose/dextrose medium, is reported in this work.
