Chronoamperometric response of Cu/CNT-Epoxy electrode recorded in 0.1 M NaOH supporting electrolyte. Chronoamperometric response of Cu/CNT-Epoxy electrode recorded in 0.1 M NaOH supporting electrolyte and by successive additions of 0.02 mM glucose without (a) and under stirring condition (b). Insets: calibration plot of peak current vs. glucose concentration. Lines in (a): 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.
