Electrochemical sensing of glucose by carbon cloth-supported Co3O4/PbO2 core-shell nanorod arrays

Electrocatalysts for Glucose Electrooxidation Reaction: A Review

“…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].…”

Nanoporous cobalt oxide nanowires for non-enzymatic electrochemical glucose detection

“…Various cobalt oxides nanostructures [19][20][21][22][23] have been used for non-enzymatic glucose sensors including nanoparticles [19], nanorods [20,22], nanofibers [21,23], and so on. Due to the large surface area provided by 1D nanostructure [24], cobalt oxide nanomaterials with 1D nanostructure for non-enzymatic glucose sensing are actively pursued at present time.…”

Effect of Urea on the Morphology of Co3O4 Nanostructures and Their Application for Potentiometric Glucose Biosensor

“…In addition to this, metal oxide nanostructures exhibit high ionic bonding property which also provides polar surfaces for the strong binding of low IEP molecules. Moreover, metal oxide nanostructures have been used for the fabrication of non-enzymatic glucose chemical sensors based on the electro-oxidation of glucose and possess high electro-catalytic properties related to their decreased size, high surface area and fast electron transfer rate [6,7]. However, the fabrication of none-enzymatic glucose sensor at physiological pH (7.3) value is a difficult and it limits the design of noneenzymatic glucose in addition of their poor selectivity.…”
