Abstract
Separation and concentration of micro/nano particles are the fundamental operations for various analyses and reactions. Here, we proposed and experimentally demonstrated a microfluidic device to concentrate and separate any charged particles using ion depletion zone. The ion depletion zone was generated in the microchannel applied by ion concentration polarization effect, which was controlled by microfluidic device with ion exchange membrane and applied voltage. This work is still primitive but we successfully demonstrated both the concentration and separation.
