    Non-enzymatic electrochemical detection of glucose with and without the presence of insulin using rGO/ZnO
    (2020) Belkhalfa, Hakim; Bendjerad, Adel; Dokhan, Nahed; Lahmar, Abdelilah; Rahmani, Salima
    In the present work, the combination of the electrophoretic deposition of ZnO nanostructures with size not exceeding 50 nm, and the reduced graphene oxide (rGO) on gold electrodes was performed to study the non-enzymatic electrochemical detection of glucose. The effect of insulin insertion on glucose detection and regulation was studied and the electrochemical responses were compared with and without this molecule. The results showed that the GO/insulin/ZnO electrode is much more sensitive for the glucose detection, in addition to its ability to drop the insulin protein hormone under a negative voltage. That bears interest as dual function sensor for detection and regulation of glucose.
