Electrochemical behaviour of dopamine at covalent modified glassy carbon electrode with l-cysteine: preliminary results

The surface of glassy carbon (GC) electrode has been modified by oxidation of L-cysteine. The covalent modified GC electrode with L-Cysteine has been studied, according the supporting electrolyte used. Favourable interactions between the L-cysteine film and DA enhance the current response compared t...
