Özet

Diabetes is known as one of the most important health problems nowadays, the numbers of diabetes

patients are increasing rapidly in the world and in our country. In this work reduced graphene oxide and

oxide nickel nanoparticles composite NiO-rGO nanocomposite was synthesized by an in situ reduction

process  which was characterized by scanning electron microscope (SEM), Fourier-transform infrared

spectroscopy (FTIR), UV-Vis spectroscopy, X-ray powder diffraction (XRD) [1]. NiO modified reduced

graphene oxide (rGO) nanocomposite (NiO-rGO) was introduced to the glassy carbon electrode (GCE)

surface for the construction of a nonenzymatic electrochemical glucose biosensor [2]. The

electrochemical properties of such a NiO-rGO modified GCE were carefully investigated. It showed a

high activity for electrocatalytic oxidation of glucose in alkaline medium. The proposed nonenzymatic

sensor can be utilized for quantification of glucose. It also exhibited good reproducibility as well as

high selectivity[3].
