چکیده

An electrochemical sensor was developed by reconstituting pyrroloquinoline quinone (PQQ), flavin adenine dinucleotide (FAD) and L-proline dehydrogenase on gold electrode. Reversible redox peaks and low redox potential were obtained from cyclic voltammograms, proved that the attached PQQ and FAD accelerated electron communication between enzyme active site and gold electrode surface. It is expected that this reconstitution technology is suitable for the application of this modified electrode to bioanode.

Electrical contacting of glucose dehydrogenase by the reconstitution of a pyrroloquinoline quinone-functionalized polyaniline film associated with an Au-electrode: an in situ electrochemical SPR study.

A novel method to generate an integrated electrically contacted glucose dehydrogenase electrode by the surface reconstitution of the apo-enzyme on a pyrroloquinoline quinone (PQQ)-modified polyaniline is described. In situ electrochemical surface plasmon resonance (SPR) is used to characterize the bioelectrocatalytic functions of the system.

Highly Sensitive Amperometric Sensor Based on Gold Nanoparticles Polyaniline Electrochemically Reduced Graphene Oxide Nanocomposite for Detection of Nitric Oxide

A sensitive electrochemical sensor was fabricated for selective detection of nitric oxide (NO) based on electrochemically reduced graphene (ErGO)-polyaniline (PANI)-gold nanoparticles (AuNPs) nanocomposite. It was coated on a gold (Au) electrode through stepwise electrodeposition to form AuNPs-PANI-ErGO/Au electrode. The AuNPs-PANI-rGO nanocomposite was characterized by Field Emission Scanning ...

The metal ion in the active site of the membrane glucose dehydrogenase of Escherichia coli.

All pyrroloquinoline quinone (PQQ)-containing dehydrogenases whose structures are known contain Ca(2+) bonded to the PQQ at the active site. However, membrane glucose dehydrogenase (GDH) requires reconstitution with PQQ and Mg(2+) ions (but not Ca(2+)) for activity. To address the question of whether the Mg(2+) replaces the usual active site Ca(2+) in this enzyme, mutant GDHs were produced in w...

Design and Optimization of a New Voltammetric Method for Determination of Isoniazid by Using PEDOT Modified Gold Electrode in Pharmaceuticals

Isoniazid (INH) was studied with regard to its electrochemical treatment on a strongly alkaline solution of a poly (3,4-ethylenedioxythiophene)-modified gold electrode, using both cyclic voltammetry and controlled potential techniques. This composite electrode exhibited 4-fold higher oxidation of INH, in accordance with peak densities, than the bare gold electrode. It was used the central compo...
