ResumoSelf-pumping porous microfluidic devices have attracted significant interest because of their low cost and broad applicability in point-of-care and low resource settings. One limitation of many of the devices is sensitivity and selectivity for detection. Electrochemistry can provide a sensitive, selective detection method while still using low cost, portable instrumentation as typified by handheld glucometers. Here, the development of electrochemical paper-based analytical devices (ePADs) is reviewed. Given the importance of electrode geometry and composition, fabrication methods are reviewed first. This is followed by a review of example applications demonstrated for ePADs. Finally, major accomplishments and future directions are summarized.
