Oxidation of l-Cysteine at a Fluorosurfactant-Modified Gold Electrode:  Lower Overpotential and Higher Selectivity

We describe the oxidation of l-cysteine (CySH) at a fluorosurfactant (i.e., Zonyl FSO)-modified gold electrode (FSO−Au). Significantly reduced anodic overpotential of CySH was observed. The FSO layer inhibited the adsorption of CySH and its oxidation products at the gold electrode surface, and the l...
