Biochemical glucose detection of the MCL. a The CV curves of the as-prepared MNS with and without 1 mM glucose at a scan rate of 10 mV s− 1. b Current change of the as-prepared MNS electrode in diverse glucose concentrations from 0 to 8 mM. c CVs of the as-prepared MNS at different scan rates from 10 to 120 mV s− 1. d Real-time amperometric responses of glucose concentrations (continuous addition of glucose at an interval of 50 s). e Selectivity test of the as-prepared MNS for Lac (1.0 mM), Vc (0.5 mM), NaCl (2.0 mM), and Glu (1.0 mM) at the potential of 0.5 V. f The reproducibility of the glucose sensor in different areas of ten samples with 1.0 mM glucose (n = 3 for each group)
