Catalase assisted Peroxide Quenching for Electrochemical Measurement of Reactive Oxygen Intermediates in Single Living Cell

Abstract

Catalase assisted peroxide quenching strategy is established by injection of catalase into a living cell using a nanopipette, which consumes intracellular hydrogen peroxide generated from the oxygen stress. Accordingly, the amounts of reactive oxygen intermediates (ROIs) are quantified at single cell level.
