Dopamine (DA) plays a significant role in the functions of the central nervous, renal, and hormonal systems. The deficiency or incompatibility of its level may lead to the symptoms of many diseases, such as cancer, Parkinson’s disease, and cardiovascular disease. Copper oxides (CuxO, x=1,2) is one of the rare non-toxic metal oxides. Due to their unique optical and magnetic properties, cuprous oxide (Cu2O) and cupric oxide (CuO), have been used to various applications suh as photocatalysis, energy conversion and storage, solar cell, gas sensors, and biosensors. Recently, graphene or reduced graphene oxide (rGO)-based electrochemical sensors have been widely used for the electrocatalytic oxidation of DA. SEM, EDS, XPS and XRD spectroscopy techniques were employed to analyze the morphological and structural characteristics of the composite materials. The resulting CuxO/ERGO nanocomposites electrodes exhibits good electrocatalytic activity toward dopamine sensing and could be used for applications in biosensor applications (low working potential (at around +0.2 V)).
