title: Wide channel dielectrophoresis-based particle exchanger with electrophoretic diffusion compensation.
abstract: We present here a microfluidic device for the chemical modification of particles. In order to alleviate diffusive mixing issues beads are pushed from a starting buffer to a reagent over a wide channel by an array of shifted electrodes. We also show that the effect of reagent diffusion can be compensated by electrophoretic forces.
