Distance-dependent quenching and enhancing of electrochemiluminescence from a CdS:Mn nanocrystal film by Au nanoparticles for highly sensitive detection of DNA.

Abstract

The quenching of electrochemiluminescence (ECL) from a CdS:Mn nanocrystal film by proximal Au nanoparticles was observed as a result of Förster energy transfer, while an enhancement of ECL takes place after hybridization with target DNA due to the energy transfer of ECL excited surface plasmon resonances in AuNPs to the CdS:Mn NCs at large separation, based on which an ultrasensitive and specific DNA biosensor was constructed.
