Summary:This paper reports a method to fabricate nanoporous junctions in microfluidic devices using off-the-shelf Nafion membrane. These nanoporous junctions are needed for various applications based on the phenomenon of ion concentration polarization (ICP). The advantages of this unique method compared to other fabrication methods of cation selective nanofluidic junctions are the simpler fabrication process, the better durability, and the increase in ICP repulsion force. Thus, microfluidic devices fabricated with that method have the potential to enhance the separation efficiency of the ICP process.
