title: A reusable potassium ion biosensor based on electrochemiluminescence resonance energy transfer.
abstract: A reusable potassium ion biosensor was reported for the first time based on the reversible DNA structural change and the interaction between surface plasmons of Au nanoparticles (NPs) and the ECL emission of CdS nanocrystals (NCs).
