Abstract
(Chemical Equation Presented) A TiO2 photoelectrode array has been designed to achieve efficient photoelectrochemical redox reactions with electron donors or acceptors during the laser desorption ionization process. By adding hydroquinone to a peptide mixture, the photoelectrochemically generated benzoquinone reacts with the cysteine residues to selectively form tagged cysteine-containing peptides, thus demonstrating that in-source oxidation reactions can be efficiently performed.
