“…In contrast, the non-enzymatic electrochemical sensing of glucose is generally based on the direct electrocatalytic oxidation of glucose on the surface of active electrode materials [7]. A variety of nanostructured transition metal-based materials have been used as electrode materials for non-enzymatic glucose sensors [10][11][12][13][14][15][16]. Compared to the traditional enzyme-based sensors, these non-enzymatic sensors offer such advantages as high stability and durability, good electric properties, simple synthesis, low cost, and possibility of mass manufacturing of high-quality sensors.…”

Mesoporous CuO microspheres with core-inhollow-shell structure were synthesized by one-pot hydrothermal method, using dicyandiamide as hydrolysis agent and poly(vinylpyrrolidone) as soft template. The assynthesized CuO microspheres were characterized by powder X-ray diffraction, field-emission scanning electron microscopy and N 2 sorption measurements. The core-inhollow-shelled CuO microspheres exhibit greatly enhanced amperometric response towards glucose as compared to that of the simple hollow counterpart. The as-developed non-enzymatic glucose sensor exhibited favorable performance with wide linear range (0.005-7.95 mM), sensitivity of 622.2 lA mM cm -2 and low detection limit of 1 lM.

“…The anodic peak (i) is because of the anodic discharge of water, with the formation of a sub monolayer of adsorbed hydroxyl radicals, while the oxidation wave (ii) is related to Au(III) formation. 43 The cathodic peaks (iii) and (iv) in the negative sweep are related to the reduction of Au(III) species. 43 However, in PBS electrolyte, no distinguishable current response for AuNPs/SPE was observed.…”

“…43 The cathodic peaks (iii) and (iv) in the negative sweep are related to the reduction of Au(III) species. 43 However, in PBS electrolyte, no distinguishable current response for AuNPs/SPE was observed. To study the effect of bulk oxide formation and reduction on Au dissolution, CV curves at various scan rates (10-200 mV s À1 ) in 1 M NaOH at AuNPs/SPE was recorded over a wider potential region (Fig.…”

“…This metabolic disorder is due to insulin shortage or high blood sugar level (hyperglycemia). This threat is observed if the blood sugar concentration is reduced or enhanced than 80–120 mg/dL (4.4–6.6 mM) . Diabetics cause heart problem, kidney failure, or loss of sight.…”

Electrochemical sensors have drawn significant attention over the last couple of decades because of their ability to improve detection of organic and inorganic analytes found in the field of biotechnology, environmental sciences, medicine, and food quality control. This personal account summarizes the state‐of‐art research carried out in the construction and evaluation of nanostructured metal oxides and zeolite based electrochemical sensors. Metal oxides and zeolite‐based nanomaterials have many unique and extraordinary properties such as tunable redox activity, surface functionalization ability, optimum conductivity, large surface area, biocompatibility and so forth. In this personal account, the current advances in electrochemical sensor applications of metal oxides, zeolite‐based nanomaterials, and their nanocomposites are described for the single and simultaneous determination of organic & inorganic contaminants present in water bodies, physiological bio‐molecules present in human blood & urine samples, and organic contaminants present in food materials.Moreover, concluding section focuses discussion on the future developments and applications of these materials in various emerging technologies.
