摘要：
A monolayer of Nile Blue (NB) has been covalently immobilized on the self-assembled thiol-monolayer modified gold electrode. Cyclic voltammograms indicated a stable and reverse redox process of NB bonded on the electrode surface. The mechanisms of redox process coupling with proton transfer were proposed. The NB-modified electrode showed excellent electrocatalytic activity toward Nicotinamide adenine dinucleotide (NADH) oxidation and horseradish peroxidase (HRP) reduction. A hydrogen peroxide biosensor based on NB as a mediator has been demonstrated.
