A new glucose biosensor based on Nickel/KH550 nanocomposite deposited on the GCE: An electrochemical study

Quick, inexpensive and accurate methods are needed for glucose determination in many biochemical and medical labs. The purpose of this study is to develop and test a novel inexpensive electrode based on nickel/gamma-aminopropyltriethoxysilane nanoparticles for measuring glucose concentrations. First, the Ni nanoparticles (Ni NPs) were synthesized by a bottom-up approach. Then, the Ni NPs and gamma-Aminopropyltriethoxysilane (KH550) were mixed at 60 °C under a nitrogen atmosphere to produce Ni/KH550 nanocomposite. Afterwards, the synthesized Ni/KH550 nanocomposites were characterized using different methods such as Fourier transform infrared (FT-IR), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD). Next, the surface of a glassy carbon electrode (GCE) was polished and washed with alumina powder and …
