Thermodynamic and Kinetic Enhancement of Electrochemical Sensitivity by Chemical Coupling in Microfluidic Systems

Abstract

One helps the other: An upstream electrode (1) in a microfluidic channel drives a reaction that produces protons so that the reaction at the downstream electrode (2) becomes thermodynamically or kinetically viable. The shift in redox potential allows the analyte to be detected in conditions in which it would otherwise be undetectable.
