Abstract
An efficient signaling on-off mechanism was first proposed by integrating exciton-plasmon coupling and exciton energy transfer into cathodic PEC bioassays. This signaling on-off mechanism has endowed the cathodic PEC biosensor with powerful capability for ultrasensitive and specific detection of target DNA.
