I-V curve for glucose sensing performances of a CO/CZO heterostructure, where (inset-i) and inset (ii) show the enlarge of lower concentrated glucose enclosed with dash-blue rectangle and calibration plot of the linear range of 0.04 mM to 8.85 mM, respectively. b Amperometric responses to the glucose concentrations varies from 0.04 mM to 34.85 mM. Inset (i) is the enlarge view of the lower concentrated glucose enclosed with dash-blue rectangle and inset (ii) is the sensor response time determined to be 4 s. c The measured data and the calibration curve of the sensor’s amperometric response to the glucose concentration, each concentration was repeated four times and the error bars indicate the deviation. Insets plots show the linear relationship between the oxidation peak current and concentration of glucose in the range of 0.04 mM to 8.85 mM and the corresponding regression equation. d The amperometric response curve of the sensing electrode to the addition of interfering agents: lactose, maltose, mannose, sucrose, and glucose in the solution. Variation in sensitivity with e mechanical deformation of 500 cycles and f immersion in electrolyte for 25 mints
