(A) CVs for the electro-polymerization of L-threonine (2.5 mM) on CPE using potential range of − 0.6 to 2.3 V with a scan rate of 0.1 V/s for 30.0 scan cycles at 0.1 M PBS (pH 9.0). (B) Effect of the number of cycles (10–40 cycles) on the anodic current. (C) The proposed electro-oxidation mechanism of AM on PTCPE.
