Cyclic voltammograms. Cyclic voltammograms of (a) Cu/SZCNT-epoxy, (b) Cu/NZCNT-epoxy, (c) Cu/CNT-Epoxy electrodes recorded in 0.1 M NaOH supporting electrolyte and after five successive additions of 0.02 mM glucose; potential scan rate 0.05 Vs−1. Insets: calibration plots of peak currents vs. glucose concentrations. Black lines, CV recorded in 0.1 M NaOH supporting electrolyte; red lines, CV recorded in 0.1 M NaOH supporting electrolyte and 0.02 mM glucose; blue lines, CV recorded in 0.1 M NaOH supporting electrolyte and 0.04 mM glucose; green lines, CV recorded in 0.1 M NaOH supporting electrolyte and 0.06 mM glucose; pink lines, CV recorded in 0.1 M NaOH supporting electrolyte and 0.08 mM glucose; and yellow green lines, CV recorded in 0.1 M NaOH supporting electrolyte and 0.1 mM glucose.
