Title: Radial Pre-Concentration With a Planar Nanoporous Film
Abstract: Electrokinetic flow in microchannels in the vicinity of charged membranes or nanochannels gives rise to a polarization phenomena that can be used to control analyte. Utilizing this concept this paper focuses on a novel method to trap and pre-concentrate an analyte surrounded by a radial planar Nafion membrane. Numerical simulations are conducted to demonstrate the exclusion enrichment phenomena and the relative effect of the convective component on concentration and electric fields is demonstrated. Preliminary experimental results demonstrate the promise of the concept.
