Electrochemical detection of peptides

Analytical Chemistry, 1989
A general method of wide applicability for the determination of peptides is described. Peptides longer than dipeptides react in the classical biuret reaction with Cu(II) to yield electroactive Cu(II)-peptide complexes that can be oxidized to the corresponding Cu(III) complexes.
