Platelet-like copper oxide nanostructures were prepared by a hydrothermal method. Various techniques like X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM) and transmission electron microscope (TEM) were used to characterize the structure and morphology of the as-prepared products. The electrocatalytic oxidation of carbohydrates and dopamine on the surface of the modified electrode were studied by cyclic voltammetry (CV), differential pulse voltammetry (DPV) and chronoamperometry (CA). Under the optimal experimental condition, the CuO nanoplatelets (CuO NPlts) loaded on glassy carbon electrode (GCE) exhibited excellent sensitivity in the linear concentration range of carbohydrates, good stability and reproducibility. Interferences from other biological compounds were studied and results indicated good selectivity for glucose, sucrose, and fructose. Apart from the detection of carbohydrates, the electrode was tested for detection possibility of dopamine in the range of 10-80 μM in phosphate buffer solution (PBS) with a detection limit of 8.25 μM. © 2014 Elsevier B.V.

An effective and sensitive non-enzymatic electrochemical glucose sensor was fabricated by the use of Ag–CuO nanocomposites, which was synthesised by a simple one step homogeneous co-precipitation route using silver nitrate and copper sulphate as precursor materials. The crystalline nature, optical properties, morphology and chemical composition of the prepared sample was determined using X-ray diffraction, diffuse reflectance ultraviolet spectroscopy, scanning electron microscope and X-ray energy dispersive spectroscopy techniques. Further the prepared composites were tested for its glucose sensing property using electrochemical technique. The electrocatalytic and electrochemical properties of the modified electrode was investigated by cyclic voltammetry. Chronoamperometric behaviour shows that the step-wise increment in current as the concentration of glucose increases from 100 to 1000 μM at a constant oxidation potential of 0.6 V(Ag/AgCl). The results indicated that the sensing properties of developed non-enzymatic biosensor shows excellent sensitivity, fast response (5 s) and good selectivity because the prepared Ag–CuO nanocomposites exhibits enhanced electrocatalytic property, fast electron transfer towards the oxidation of glucose. © 2018, © 2018 Informa UK Limited, trading as Taylor &amp; Francis Group.

CuS nanostructures have been prepared by hydrothermal route using copper nitrate and thiourea as copper and sulfur precursors. Investigations were done to probe the effect of cationic surfactant viz. cetyl trimethyl ammonium bromide on the morphology of the products. Further studies have been done to know the influence of reaction time on the morphology of CuS nanostructures. Results demonstrated that the morphology of CuS was influenced by the reaction time and surfactant. X-ray diffraction pattern showed that the as-prepared CuS nanostructures were in pure hexagonal phase and UV-vis spectra reveal a strong absorption in the visible region of 400-800. nm. A detailed mechanism has been elucidated for the growth of CuS nanostructures. The photocatalytic activity was evaluated by the decolorization of methylene blue (MB) dye under visible-light irradiation and results showed that 87% of the dye was degraded. Thus the as-prepared CuS catalysts are highly promising materials for photocatalytic applications towards dye degradation. © 2013 Elsevier B.V.
