“…Also in this case the location of the peak is in good agreement with the results obtained by Feng [30]. Pasta et al suggested that long left shoulder of this voltammograms corresponds to several different processes taking place at similar potentials.…”

“…It can be noted that independently of kind of catalyst used in the experiments three peaks were observed. For GC-gold catalyst (Figure 11(b)) first peak was observed at the potential −0.42 V. Location of this peak agrees with the results obtained by Feng [30] who performed experiments in 0.1 M NaOH using gold nanoparticle-chitosan composite film as a catalyst. Pasta and co-workers [25,31], suggested that this peak can be attributed to dehydrogenation of anomeric carbon, in good agreement with the results of Basu et al [24].…”

In this study the catalytic properties of gold nanoparticles in electro-oxidation process of glucose, were investigated, taking into account, an influence of catalyst composition. Graphene oxide was applied and for electro-oxidation studies of glucose, cyclic voltamperometry was used. It was found that an application of graphene oxide sheets during catalyst synthesis have an influence on gold nanoparticles (AuNPs) size and size distribution. It was confirmed that the application of composite catalyst consisting of graphane-AuNPs significantly changes electro-oxidation of glucose shifting the potential of oxidation to higher positive values and increasing oxidation current.

Abstract:A novel clinical glucose biosensor fabricated using functionalized metalloid-polymer (silver-silica coated with polyethylene glycol) hybrid nanoparticles on the surface of a graphene oxide nanosheet is reported. The cyclic voltammetric response of glucose oxidase modification on the surface of a functionalized graphene oxide electrode showed a surface-confined reaction and an effective redox potential near zero volts, with a wide linearity of 0.1-20 mM and a sensitivity of 7.66 µA mM. The functionalized graphene oxide electrode showed a better electrocatalytic response toward oxidation of H 2 O 2 and reduction of oxygen. The practical applicability of the functionalized graphene oxide electrode was demonstrated by measuring the peak current against multiple urine and serum samples from diabetic patients. This new hybrid nanoarchitecture combining a three-dimensional metalloid-polymer hybrid and two-dimensional graphene oxide provided a thin solid laminate on the electrode surface. The easy fabrication process and retention of bioactive immobilized enzymes on the functionalized graphene oxide electrode could potentially be extended to detection of other biomolecules, and have broad applications in electrochemical biosensing.

Poly(1-amino-9,10-anthraquinone-co-o-phenylenediamine) (P1AAQ-co-POPD) was synthesized by electrochemical methods on stainless steel electrodes (SS) using equal monomer concentration in acetonitrile/acidified water mixture as solvent. Electrochemical characterization allows, among others, determining the characteristic redox couple potential of the quinone group, which is one of the advantages of having achieved the copolymerization. FTRaman, ATR and UV-Vis characterization confirms the formation of the copolymer, particularly, by the occurrence of a novel signal ascribed to a new C-N type bond. Besides, the conductivity of the deposits was determined, which enabled the conducting properties of the products to be verified. The topographical and morphological characterization accomplished by atomic force (AFM) and transmission electron (TEM) microscopy showed how the inclusion of o-phenylenediamine (OPD) increases the homogeneity of the copolymer, which in turn enables designing likely applications of the electrode modified with this novel polymeric material.
