(A) Voltage perturbation for two sequential potential step experiments; (B) Overlaid charge collected for the two potential steps; (C) Background subtracted (difference) charge collected at the enzyme modified electrode (red) and bare electrode (black) at the cell (1, 2, 3 indicate the chronological order); (D) Average difference charge for four consecutive determinations at the cell and cyclodextrin (500 μM for one hour) treated cell using the enzyme modified electrode and bare electrode (difference charge taken at 1 second).
