Cyclic voltammetry experiments performed on the amorphous carbon electrode (black line) on the electrode modified with a (PAH-MMT)10-PAH film (blue line) and on the same film after 14 h of reaction with dopamine (red line), the reaction being performed with dopamine at 2 g L−1 in the presence of 50 mM Tris buffer at pH 7.5. The redox probe was K4Fe(CN)6 at 1 mM in the presence of Tris 50 mM + NaCl 150 mM at pH 7.5
