Voltage-gated Metal-enhanced Fluorescence, Chemiluminescence Or Bioluminescence Methods and Systems

In the present invention, it is demonstrated for the first time, the influence of electrical current on the ability of surface plasmons to amplify fluorescence signatures. An applied direct current across silver island films (SiFs) of low electrical resistance perturbs the fluorescence enhancement of close-proximity fluorophores. For a given applied current, surface plasmons in "just-continuous" low resistance films are sparsely available for fluorophore dipole coupling and hence the enhanced fluorescence is gated as a function of the applied current.
