“…As with DGFCs, many attempts of the research community have also been focused unsuccessfully on the development of enzyme-based biosensing glucose electrochemical devices. The need that the main disadvantages of the enzyme-based biosensors, such as instability, high cost of enzymes and many others [7][8][9] be overcome, led to the non-enzymatic (catalytic) amperometric biosensors. The simplicity, higher sensitivity and lower cost of the latter have drawn much attention [10].…”

Electrocatalysts for Glucose Electrooxidation Reaction: A Review

The up-to-date research as far as it concerns the abiotic direct glucose fuel cells (DGFCs) is summarized and discussed in the present review. Platinum and goldbased as well as Raney-type electrocatalysts are among the most studied ones. In abiotically (non-implantable) DGFCs, unsupported Pt and PtRuO 2 , exhibited good activity (power density *20 mW cm -2 ), at room temperature and at atmospheric pressure. On the other hand, Au-based electrocatalysts adopted in a DGFC resulted in power densities up to ca. 5 mW cm -2 , exhibiting however high poisoning tolerance. Recently, after the introduction of alkaline membranes into the market, Pd-based electrocatalysts have attracted the attention of the research community because of their enhanced activity in alkaline media. However, there are still very few investigations where membrane electrode assemblies with palladium electrocatalysts have been applied. Moreover, Raney-type electrocatalysts, not yet examined for other fuels in direct polymer electrolyte fuel cells, are considered to be the most appropriate for implantable abiotic DGFCs. A novel implantable fuel cell in a human brain performed with 3.4 9 10 -3 lW power for 10 h adopting Raney-type electrocatalysts.

“…There have been developed glucose sensors using different nanomaterials including platinum, gold, palladium, and metal oxides [1,[4][5][6]. Among them, due to biocompatibility, higher activity, and lower potential of glucose electrooxidation, gold is one of the most inspiring materials for the fabrication of glucose sensors [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26].…”

Hyperbranched pine-like gold nanostructure was electrodeposited on the polycrystalline gold surface at 0 mV (vs. AgCl) with the assistance of histidine as a soft template. The nanostructure was then applied as a highly sensitive nonenzymatic sensor for glucose. The catalytic activity and sensitivity of the gold nanostructure toward the electrooxidation of glucose was excellent without surface fouling and deterioration effects. The current related to the oxidation of glucose rapidly and linearly depended on its concentration with a sensitivity of 776.8 μA cm(-2)mmol(-1)dm(3), a detection limit of 3.39 μmol dm(-3) with a relative standard deviation of 2.32%.

“…Non-enzyme CNT-based biosensors for glucose detection also evolved by dispersing nickel and copper nanoparticles instead of enzyme on the MWCNT electrode [166] can effectively analyze glucose concentration in human serum. Gougis et al reported another kind of non-enzymatic glucose biosensor by depositing gold nanostructures onto CNT electrode with remarkable performance [167].…”

In recent years, integrating biological components in analytical instruments especially in biomedical research has become a prerequisite for early diagnosis of many diseases. It is well known that the material properties (electrical and physical) of CNTs is very sensitive to be affected by exposure to biomolecules and this led to the investigation by many researchers. Though the CNT-based biosensors has been widely used due their better performance, it still has many practical concerns in application. For the successful commercialization of the concept of CNT-based biosensors, many hurdles need to overcome. Modifications on CNT biosensors have experienced a dramatic change with outstanding developments. The present article provides an overview on the recent development in CNT biosensors and comprehensive analysis was given on various ways to improve the performance of CNT with new designs. In addition, some of the practical applications and concerns in the field are addressed. The scientific and technological challenges in the field are discussed in the conclusion.
