a Cyclic voltammetry (CV) of NiO-NPs@FTO on various scan rates. b Elctrochemical glucose(10 μM) sensing using CV technique. c CV scan of glucose immobilized NiO-NPs@FTO electrode at various scan rates. b Electrochemical impedance spectroscopy (EIS) to show glucose sensing. Insets in a and c show a linear variation of current as a function of scan rate
