We observed a strong, more than 16-fold, enhancement of Texas Red-labeled BSA fluorescence emission when deposited on silver colloid coated surfaces (SCCS). The same labeled protein deposited on silver island films (SIFs) showed an approximate 8-fold fluorescence enhancement. The lifetimes of Texas Red-BSA fluorescence are significantly shorter on silvered surfaces than on uncoated quartz substrate indicating a strong change in radiative decay rate of the dyes. We also observed a 36-fold increased brightness of overlabeled fluorescein-HSA deposited on silver colloid coated surface. Stronger enhancement observed for overlabeled Fl-HSA protein indicates that presence of silver particles partially decreased self-quenching. Our results indicate that surfaces coated with silver colloids are valuable substrates for metal-enhanced fluorescence.

“…The observed oscillations of lifetimes with distance in front of a mirror can be explained by changes in the phase of the reflected light field with distance [2]. The decreased emission rate of fluorophores between closely spaced mirrors was observed and interpreted as effects in cavity quantum electrodynamics [3][4][5].…”

“…When studying the interaction of emissive species such as quantum dots 103 and wells, 101 fluophores 105 or rare-earth ions 106 with metallic surfaces, 107 gratings 105 or nanoparticles, 108 special care must be taken for a distinction between radiative and nonradiative contributions to the total enhanced decay rate. The huge increase of the non-radiative decay rate observed for emissive species placed in nanometric distances to metallic surfaces makes the design of plasmonic cavities for emissive devices challenging, 109 but promising routes for the creation of efficient emissive devices such as light-emmiting diodes ͑LEDs͒ based on SPPsupporting cavities have been developed 110,111 and partly demonstrated.…”

We review the basic physics of surface-plasmon excitations occurring at metal/dielectric interfaces with special emphasis on the possibility of using such excitations for the localization of electromagnetic energy in one, two, and three dimensions, in a context of applications in sensing and waveguiding for functional photonic devices. Localized plasmon resonances occurring in metallic nanoparticles are discussed both for single particles and particle ensembles, focusing on the generation of confined light fields enabling enhancement of Raman-scattering and nonlinear processes. We then survey the basic properties of interface plasmons propagating along flat boundaries of thin metallic films, with applications for waveguiding along patterned films, stripes, and nanowires. Interactions between plasmonic structures and optically active media are also discussed.

“…[1][2][3][4] This interest has its origins in the pioneering studies of Drexhage on the effects of mirrors on nearby fluorophores 5,6 and subsequent studies by Barnes and co-workers. [7][8][9] In this laboratory, we have studied the favorable effects of silver particles on fluorophores. These effects include increased quantum yields, decreased lifetimes, and increased photostability of fluorophores commonly used in biological research.…”

Electrochemical and Laser Deposition of Silver for Use in Metal-Enhanced Fluorescence

We describe two reagentless methods of silver deposition for metal-enhanced fluorescence. Silver was deposited on glass positioned between two silver electrodes with a constant current in pure water. Illumination of the glass between the electrodes resulted in localized silver deposition. Alternatively, silver was deposited on an Indium Tin Oxide cathode, with a silver electrode as the anode. Both types of deposited silver produced a 5-18-fold increase in the fluorescence intensity of a nearby fluorophore, indocyanine green (ICG). Additionally, the photostability of ICG was dramatically increased by proximity to the deposited silver. These results suggest the use of silver deposited from pure water for surface-enhanced fluorescence, with potential applications in surface assays and lab-on-a-chip-based technologies, which ideally require highly fluorescent photostable systems.
