Abstract
The electrochemical oxidation of ascorbic acid (AA) and dopamine (DA) at a gold electrode modified with a self-assembled monolayer (SAM) of cystamine (CYSA) has been studied. A large decrease in the overpotential for the oxidation of AA was noticed at CYSA-Au electrode. Well-separated square wave voltammetric peaks for AA and DA were observed at this electrode, which can be used for the simultaneous detection of these species.
