Electrochemical properties of Nile Blue covalently immobilized on self-assembled thiol-monolayer modified gold electrodes.

چکیده
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.

متن کاملSelf-Assembled Monolayer of Thiols on Gold Electrodes Prepared by Gold Electro-chemical Deposition on Platinum Wire
The gold electrodes modified with organic compounds (frequently organic thiols and their derivates), represent a new category of devices which are widely used in molecular recognition, in special in case of biomolecules analysis. Alkanethiols are spontaneously adsorbed on the gold surface and form a monomolecular film, with a highly ordered structure, called a self-assembled monolayer (SAM). Th...
متن کاملDetermination and stripping of lead ions at disorganised self-assembled monolayer modified gold piezoelectrode
Deposition and stripping of lead ions at thiol based disorganised monolayer modified gold piezoelectrodes was studied by cyclic voltammetry (CV) and electrochemical quartz crystal nanobalance (EQCN). Gold electrodes modified with 3-mercaptopropionic acid and 1,3-dimercapto propane sulphonic acid were studied. Due to the proximity of the potentials for the Pb deposition and thiol reductive desor...
متن کاملAn electrochemical immunosensor using p-aminophenol redox cycling by NADH on a self-assembled monolayer and ferrocene-modified Au electrodes.
Redox cycling of enzymatically amplified electroactive species has been widely employed for high signal amplification in electrochemical biosensors. However, gold (Au) electrodes are not generally suitable for redox cycling using a reducing (or oxidizing) agent because of the high background current caused by the redox reaction of the agent at highly electrocatalytic Au electrodes. Here we repo...
