(a) Chronoamperometry curves and (b) the calibration curves (current density versus glucose concentration) for the amperometric responses of seamless S/NPG and fresh and reused S/NPG/Co3O4 microelectrodes to the successive addition of glucose with the concentrations from 1 μM to 10 mM in 0.5 M KOH solution at a constant potential of 0.26 V (versus Ag/AgCl). (c) Fast response of seamless S/NPG/Co3O4 hybrid microelectrode to 1 and 10 μM glucose. (d) Glucose sensitivities of seamless S/NPG and fresh and reused S/NPG/Co3O4 microelectrodes as a function of the concentration of glucose.
