Abstract

In this work, Poly (adenine) film modified carbon nanotube paste electrode (PAEMCNTPE), prepared by Electropolymerization of adenine on a carbon nanotube paste electrode, applied for the sensitive and selective analysis of Dopamine (DA), Uric acid (UA) and Ascorbic acid (AA) based on cyclic voltammetric technique. The Polyadenine modified carbon nanotube paste electrode has presented with an impressive electrocatalytic activity towards oxidation of DA, UA, and AA in the presence of supporting electrolyte, 0. 2 M PBS pH 6. 5. The surface of fabricated sensor displayed with a permselective layer with transducing, anti-interfering and anti-fouling properties followed by solving the overlapped peaks of DA, AA and UA obtained from the conventional electrode by presenting with distinct three anodic peaks. The result of this electrochemical sensor displayed with excellent sensitivity, selectivity, reproducibility, repeatability and highly stable. The detection limit for DA was 6. 7×10-7 M. Further; this fabricated electrode was carried out for the quantification of DA in the real sample.
