Abstract

The surface-enhanced Raman spectroscopy of bilirubin at a silver electrode is investigated in aqueous solution. Bilirubin is found to be adsorbed at the electrode as its dicarboxylate anion. Only one pyrro-methenone moiety per molecule contributes to the observed spectrum. SERS from the albumin complex is not observed, suggesting that bilirubin is completely enclosed by this protein.
