Figure 6

SWVs of 2,7-BFGPE in 0.1 M PBS (pH 7.0) containing different concentrations of methyldopa. Numbers 1 to 13 correspond to 0.09, 0.5, 1.0, 2.5, 5.0, 10.0, 15.0, 50.0, 100.0, 200.0, 300.0, 400.0, and 500.0 μM of methyldopa, respectively. Inset: plots of the electrocatalytic peak current as a function of methyldopa concentration in the range of 0.09 to 15.0 μM (A) and 15.0 to 500.0 μM (B).
