Fluorescence based commercial sensing platforms and point-of-care devices are widely used. However, the major drawbacks of conventional fluorescence technique are its low collection efficiency (<1%) arising on account of its isotropic emission, interference by scattered light, photo-bleaching of the fluorophore and a congested fluorescence emission spectrum.
In this regard, Surface Plasmon-Coupled Emission (SPCE) platform presents a synergy of plasmonics and fluorescence technologies to overcome these drawbacks. They offer A) Emission enhancements, B) Polarized emission and C) Angular emission with spectral deconvolution. We pioneered in the usage of various nano materials as spacer and cavity materials towards realizing >1000-fold enhancement of fluorescence emission.
