“…Sivayogam et al presented the difference in crystallinity owing to the different calcination temperatures as the final step during the sol-gel preparation of CuO nanomaterials. Particles obtained from calcination at 700 • C were more crystalline than those obtained at 500 and 300 • C and hence presented well-defined peaks in the XRD diffractograms [38].…”

Millions of people worldwide are affected by diabetes, a chronic disease that continuously grows due to abnormal glucose concentration levels present in the blood. Monitoring blood glucose concentrations is therefore an essential diabetes indicator to aid in the management of the disease. Enzymatic electrochemical glucose sensors presently account for the bulk of glucose sensors on the market. However, their disadvantages are that they are expensive and dependent on environmental conditions, hence affecting their performance and sensitivity. To meet the increasing demand, non-enzymatic glucose sensors based on chemically modified electrodes for the direct electrocatalytic oxidation of glucose are a good alternative to the costly enzymatic-based sensors currently on the market, and the research thereof continues to grow. Nanotechnology-based biosensors have been explored for their electronic and mechanical properties, resulting in enhanced biological signaling through the direct oxidation of glucose. Copper oxide and copper sulfide exhibit attractive attributes for sensor applications, due to their non-toxic nature, abundance, and unique properties. Thus, in this review, copper oxide and copper sulfide-based materials are evaluated based on their chemical structure, morphology, and fast electron mobility as suitable electrode materials for non-enzymatic glucose sensors. The review highlights the present challenges of non-enzymatic glucose sensors that have limited their deployment into the market.

“…Copper oxide nanoparticles (CuO NPs) are a type of metal oxide nanoparticles that have potential applications in both science and industry [12][13][14][15]. Various techniques for synthesizing CuO NPs include sonochemical methods [16], chemical precipitation [17], laser ablation in liquid [18], hydrothermal [19], sol-gel [20], and more. The chemical synthesis methods mentioned above are highly effective but have several limitations, such as high costs, utilization of hazardous chemicals and solvents, production of toxic waste, and high energy requirements.…”

In this study, Melia azedarach fruit extract was used as a reducing agent and copper chloride dihydrate (CuCl2·2H2O) was used as a precursor in the synthesis of copper oxide nanoparticles (CuO NPs). The UV–visible spectrum showed a characteristic absorption peak of CuO NPs at 350 nm. The surface properties of the adsorbent were analyzed through various techniques, indicating the successful formation of CuO NPs. The impacts of several factors, including initial pH (4 to 8), a dose of CuO NPs adsorbent (0.01–0.05 g), dye initial concentration (10–50 mg·L−1), and contact times ranging from 5 to 120 min, were examined in batch adsorption studies. Based on the experimental results, the Langmuir isotherm is well-fitted, indicating MB dye monolayer capping on the CuO NPs surface with 26.738 mg·g−1 as a maximum adsorption capacity Qm value. For the pseudo-second-order kinetic model, the experimental and calculated adsorption capacity values (qe) exhibited good agreement.
