Here we present for the first time the implementation of Flow-Induced Electrokinetic Trapping (FIET) for the quantitative separation of polymer microparticles in microfluidic channels. FIET is a particle-trapping mechanism that depends on the generation of recirculating flows in non-uniform microchannels. Polymer microspheres captured in recirculating flows can be separated based on differences in charge and size, leading to a chip-based separation technique called tunable hydrodynamic chromatography (THC). We have harnessed FIET to realize a new methodology for particle separation. Quantitative separations (≥99%) of microspheres have been achieved within less than 10 minutes.
