The International Debate on Metal and Non-Metal Doped Cuo for Glucose Sensing
Various alloys and noble metals perform well in the development of non-enzymatic electrochemical sensors, but they are expensive, poisonous and undergo energy reduction when being used. Metal oxides are suitable alternatives for glucose detectors as they are available, affordable, stable, easy-to-use and provide a large surface area. Some metal oxides that has been employed in designing non-enzymatic electrochemical sensors include; Co3O4, CuO, ZnO, SnO and NiOH2 etc. Copper oxide (CuO) is particularly interesting among others as it is a readily available semiconducting compound affiliated with the monoclinic crystal system. CuO is an inexpensive p-type semiconductor characterized by an array of functional physical and chemical properties, including high temperature superconducting properties and electron correlation effects. Copper oxide has been widely studied for various applications owing to its superior electrocatalytic capability, glucose oxidation, exceptional resilience and its eco-friendliness. CuO has been utilised in catalysts, electronics, solar cells, storage devices, and thermal transfer fluids.
