“…Moreover, high working potentials mean high energy consumption. Substrate contamination by adsorbed molecules on the flat surface is another disadvantage usually met [8,9]. To overcome these problems, the development of hybrid nanomaterials have attracted high interest for the combination of the properties of each component that exhibit better catalytic performance than the single component [10].…”

Abstract-In this work we describe the realization of monometallic nanostructures by two simple electrodeposition steps. The surface of the modified electrode was characterized by scanning electron microscopy that confirms a homogeneous deposition of Pt nanospheres decorated with Pt nanoflowers. The so obtained nanostructured sensor exhibited good amperometric response towards hydrogen peroxide sensing at +0.30 V vs Ag|AgCl|Cl -. Therefore, it is especially useful toward glucose detection with reduced interferences. Glucose oxidase was immobilized onto the nanostructured surface by cross-linking with glutaraldehyde and the biosensor was characterized by chronoamperometric method in phosphate buffer. The biosensor showed a sensitivity of 29 ± 2 μA/(mM cm 2 ). Measurements in cell media reveal that the Pt-Pt hybrid nanostructures are promising for real-time glucose monitoring in real biosample.

“…The performance of the gold catalysts can be improved by employing the right concentrations of gold salts and reducing agents to prepare gold nanoparticles and also by preparing bimetallic or trimetallic gold catalysts like Ag-Au [14], Pt-Au [9] or Au-Pt-Ag [15] to improve the catalytic activity of gold catalysts for glucose oxidation. Pt-Au catalysts have been shown to have reduced poisoning of platinum.…”

“…Another group of researchers developed glucose fuel cell using commercial Pt-Ru/C as anode catalyst with 1.38 mW cm -2 peak power density [8]. The same group developed Pt-Au/C catalyzed fuel cell that reduced the poisoning level of platinum and generated 0.72 mW cm -2 peak power density [9]. Biella et al found that gold was much more active than commercial Pt-Pd-Bi or Pd-Bi catalysts that were specifically designed for glucose oxidation.…”

Considerable research attention has been given to glucose biofuel cells as they have been recognized for their ability to work under ambient temperatures and a range of pH that makes them suitable for in vivo implantation to power, with body glucose, implantable electronic devices. In this work, we have employed a different approach compared to organic enzymes to facilitate the fabrication of biofuel cell with no organic enzymes. Gold and platinum nanoparticles were synthesized as oxidizing agents and compared their effectiveness in our fabricated biofuel cell. The nanoparticles were placed on a conductive carbon structure. We have found that the gold nanoparticles are more effective as catalyst capable of converting glucose into gluconic acid compared with that of platinum particles. We further found that the concentration of nanoparticles in the cell may not benefit the catalysis of the glucose due to the decrease of surface area to volume ratio as the nanoparticles' concentration increases. Our fabricated fuel cell showed a capability of running multiple cycles, once the medium is adjusted to optimal operation conditions.

“…According to the literature (Basu and Basu, 2011), there were some reactions taking place on the surface of Pt catalyst in alkaline media in different potential regions which after addition of glucose caused three different types of glucose oxidation on the surface of Pt catalyst. This fact resulted in not only the presence of different oxidation reduction region in the response curve of Pt NWAs (curve 4), but also the whole rise causing from glucose addition in curve 5 in compared to curve 4.…”
