Metal-enhanced fluorescence: effect of surface coating
SPIE Proceedings, 2014Metal Enhanced Fluorescence (MEF), a phenomenon arising when a fluorophore is in closed proximity to a metallic structure such as metallic films or nanostructures, is seen as a way to increase the amount of reactive oxygen species produced by the irradiation of the protoporphyrin IX (PpIX), a photosensitizer commonly used in photodynamic therapy. Here,

The tuning of metal enhanced fluorescence for sensing applications
Dalton Trans., 2014Stable coinage metal nanoparticles (NPs) have been synthesized individually in an aqueous alkaline solution from the corresponding metal salts as precursors using the condensation product (CP) of salicylaldehyde and triethylenetetramine as a reagent. Silver and gold NPs are obtained with and without light illumination but UV irradiation is essential ...

Metal-Enhanced Fluorescence: Potential Applications in HTS
Combinatorial Chemistry & High Throughput Screening, 2003Metallic surfaces and particles can have dramatic effects on fluorescence, including localized excitation, increased quantum yields, increased photostability and increased distances for resonance energy transfer (RET), and directional emission. While all these effects have not yet been realized in a single system, metal-enhanced fluorescence promises ...

Enhancing the analytical performance of immunoassays that employ metal-enhanced fluorescence
Analytical and Bioanalytical Chemistry, 2009In this work, we used a model assay system (polyclonal human IgG-goat antihuman IgG) to elucidate some of the key factors that influence the analytical performance of bioassays that employ metal-enhanced fluorescence (MEF) using silver nanoparticles (NPs).

Nanosphere Templated Metallic Grating Assisted Enhanced Fluorescence
Journal of Fluorescence, 2011In this paper, enhanced fluorescence from a silver film coated nanosphere templated grating is presented. Initially, numerical simulation was performed to determine the plasmon resonance wavelength by varying the thickness of the silver film on top of a monolayer of 400 nm nanospheres.

Wavelength Dependence of Metal-Enhanced Fluorescence
The Journal of Physical Chemistry C, 2009In this paper, metal-enhanced fluorescence (MEF) from 6-propionyl-2-dimethylaminonaphthalene (Prodan) in different solvents when placed in close proximity to silver island films (SIFs), surface-deposited nanoparticles, is studied. We observe that MEF is wavelength dependent: the enhanced emission of Prodan on SIFs in different solvents changes from 1.5-
