Plasmon-enhanced fluorometry based on gold nanostructure arrays. Method and device

In this work, we describe a method of surface-enhanced fluorometry, based on the phenomenon of localized surface plasmon resonance in unordered gold nanostructure arrays. The theoretical approach for the model system “gold nanoparticle-dielectric spacer” in the electrostatic approximation by solutio...
