Construction of self-enhanced photoelectrochemical platform for l-cysteine detection via electron donor–acceptor type coumarin 545 aggregates

Abstract

Self-enhanced electron donor–acceptor type coumarin 545 aggregates prepared via an anionic surfactant-assisted reprecipitation method provide an underlying approach for the photoelectrochemical detection of L-cysteine, which can be employed in aqueous solution without the addition of electron donors.
