Abstract

We present the use of Flow-Induced Electrokinetic Trapping (FIET) to achieve simultaneous, orthogonal, single-channel size- and charge-based fractionation of mixtures of polymer microspheres. Fractionation is performed in glass microchannels of non-uniform cross-section using stepwise applied voltage and pressure programs.
