Cao SH, Cai WP, Liu Q, Xie KX, Weng YH, Li YQ. Turning on fluorescence by plasmonic assembly with large tunable spacing: a new observation and its biosensing application. Chem Commun (Camb). 2013;.
Assembling nanoparticle-film metallic junctions with a spacing of up to tens of nanometers efficiently turned on fluorophores attached to the film from the quenching status to an intense surface plasmon-coupled emission. Benefiting from this new finding, a fluorescence biosensor was created based on the use of a biomolecule-linked plasmonic assembly as the trigger.
