Electrokinetic concentration enrichment within a microfluidic device using a hydrogel microplug.

Abstract

A simple and efficient approach for concentration of charged molecules in microfluidic devices is described. The functional component of the system is a hydrogel microplug photopolymerized within the main channel of a microfluidic device. When an appropriately biased voltage is applied across the hydrogel, charged analyte molecules move from the source well… (More)
