A novel electrochemical assay for aspartame determination via nucleophilic reactions with caffeic acid ortho-quinone

Cyclic voltammetry (CV) in a pH 7.0 phosphate buffer solution containing aspartame (ASP) and caffeic acid (CAF) was studied. In sharp contrast to untreated electrodes, two distinct redox peaks were observed at preanodized screen-printed carbon electrodes (SPCE*) due to the formation of a homopolymer...
