Abstract

We present a high-speed particle sorting and deflection system which is an integral part of a micro-flow cytometer chip capable of high speed detection and sorting of micron sized particles. The device sorts particles using a combination of DEP and hydrodynamic forces. DEP focussing of particles is used to axially centre particles in a channel. Negative dielectrophoresis together with hydrodynamic flow is used to achieve high speed particle sorting at a microfluidic T-junction.
