Abstract

Abstract : We develop MoS2 and quercetin functionalized nanoelectrodes with excellent electrocatalytic and anti-sulfur poisoning performance for H2 S detection. Utilizing such nanosensors, the accurate quantification of intracellular endogenous H2 S was achieved. Abstract : Intracellular H2 S plays an important regulatory role in cell metabolism. The limited sensing materials and severe sensor passivation hinder its quantification. We functionalized conductive nanowires with MoS2 and quercetin in a large-scale manner, developed single nanowire sensors with excellent electrocatalytic and anti-poisoning performance, and achieved the accurate quantification of H2 S within single cells.
