Abstract : Diabetes is one of the fastest growing diseases worldwide that can lead to dangerous complications. Therefore, the demand for the development of optimal glucose sensors has increased for diabetes disease management. The purpose of this study was to develop a simple, rapid, low-cost, highly sensitive and selective non-enzymatic glucose sensor for determination of glucose in the serums of healthy controls and diabetic patients. In this study, a non-enzymatic glucose sensor based on reduced graphene oxide and nickel oxide (rGO/NiO25 and rGO/NiO50) nanocomposites were developed. These novel nanocomposites were synthesized using a facile and rapid green economic microwave-assisted hydrothermal method in the absence of auxiliary agents. The morphology and composition of the as-prepared nanocomposites were characterized via X-ray diffraction, Fourier transform infrared, energy-dispersive X-ray spectrometry, and field emission scanning electron microscopy. The electrochemical performance of the rGO/NiO50-modified electrode was examined by cyclic and square wave voltammetric techniques under optimal conditions. The results indicated that the developed rGO/NiO50 electrode exhibited a good performance toward glucose detection. The fabricated sensor was also investigated for the detection of glucose in the presence of common interfering species. Thus, the sensor exhibited good sensitivity, selectivity, repeatability, and stability alongside its economical application as a non-enzymatic glucose sensor. Additionally, the proposed sensor was successfully applied for glucose detection in human serum samples with satisfactory recoveries.
