Sensitive Detection of Silver Ions Based on Chiroplasmonic Assemblies of Nanoparticles

The formation of an optically active plasmonic assembly through DNA recognition mediated by silver ions is reported, and a sensitive and selective chiroptical detection system is fabricated with a detection limit of approximately 2 pM for silver ions.
