“…[8][9][10][11] Amperometric measurements allow observation of the electrochemical oxidation of glucose on a bare platinum (Pt) surface. [3][4][5] Therefore, many nonenzymatic biosensors have been advocated, especially, amperometric glucose sensors free from enzymes. [6][7]12] However, even the state-ofthe-art technology for glucose sensing with Pt electrodes is not free from poisoning by adsorbed intermediates, [13] resulting in poor selectivity for direct glucose detection.…”

A three-dimensionally ordered, macroporous, inverse-opal platinum film was synthesized electrochemically by the inverted colloidal-crystal template technique. The inverse-opal film that contains platinum nanoparticles showed improved electrocatalytic activity toward glucose oxidation with respect to the directly deposited platinum; this improvement is due to the interconnected porous structure and the greatly enhanced effective surface area. In addition, the inverse-opal Pt-film electrode responds more sensitively to glucose than to common interfering species of ascorbic acid, uric acid, and p-acetamidophenol due to their different electrochemical reaction mechanisms. Results showed that the ordered macroporous materials with enhanced selectivity and sensitivity are promising for fabrication of nonenzymatic glucose biosensors.

“…Glucose can be electrochemically oxidized to gluconic acid at a platinum electrode. In this reaction, some intermediates (e.g., adsorbed CO) are formed [13,14], which poison the electrode surface, resulting in low sensibility and poor selectivity. The oxidation mechanism of glucose at platinum electrode is similar to that of ethanol.…”

PtRu nanoparticles were supported on multiwall carbon nanotubes (MWNTs), which were further fabricated as an electrode for nonenzymatic glucose sensing. Transmission electron microscope and X-ray diffraction patterns were used for characterization of the PtRu nanoparticles on MWNTs. Cyclic voltammetry and chronopotentiometry were applied to investigate the performance of the PtRu/MWNTs nanocomposite electrode for nonenzymatic oxidation of glucose. The PtRu/MWNTs electrode shows high electrocatalytic activity towards the oxidation of glucose in 0.1 M NaOH solution and thus can be used to selectively detect glucose. Under the optimal potential (þ 0.55 V vs. Ag/AgCl) , the biosensor effectively performs a selective electrochemical analysis of glucose in the presence of common interferents, such as ascorbic acid (AA), dopamine (DP) and uric acid (UA). Wide linear calibration ranging from 1 mM to 15 mM, high sensitivity of 28.26 mA cm À2 mM À1, low detection limit of 2.5 Â 10 À5 M, and fast response time of 10 s were achieved for the detection of glucose at the PtRu/MWNTs electrode.

“…To increase the efficiency of this process the application of catalyst is required. As a catalyst material the metal nanoparticles [20][21][22] or enzyme can be used. In fact, in the literature there is a significant number of publications, containing information about potential application of sugar in alkaline fuel cells (AFC) [23][24][25].…”

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.
