a The current response of NiO HPA electrode to sequential addition of 50 μM glucose and 5 μM interfering species at an applied potential of 0.6 V. Inset is the statistical data of the interference current. b Long-term stability of NiO HPA electrode for 0.1 mM glucose. Inset is the stability of NiO HPA electrode with the running time. c Current responses of five NiO HPA electrodes towards 0.1 mM glucose. d Ten measurements of a NiO HPA electrode towards 0.1 mM glucose
