Metal-enhanced fluorescence exciplex emission
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2012In this letter, we report the first observation of metal-enhanced exciplex fluorescence, observed from anthracene in the presence of diethylaniline. Anthracene in the presence of diethylaniline in close proximity to Silver Island Films (SIFs) shows enhanced monomer and exciplex emission as compared to a non-silvered control sample containing no silver ...

Low Temperature Metal-Enhanced Fluorescence
Journal of Fluorescence, 2007In this short letter, we describe the effects of low temperature on the Metal-Enhanced Fluorescence (MEF) phenomenon. Fluorophores close to Silver Island Films (SiFs) show on average two- to ten-fold enhancements in their fluorescence signatures at room temperature.

Voltage-Gated Metal-Enhanced Fluorescence
Journal of Fluorescence, 2009We demonstrate 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.

Metal-Enhanced Fluorescence from Plastic Substrates [PDF]
Journal of Fluorescence, 2005 We report the first findings of Metal-Enhanced Fluorescence (MEF) from modified plastic substrates. In the past several years our laboratories have reported the favorable effects of fluorophores in close proximity to silver nanoparticles. These effects include, enhanced fluorescence intensities, (increased detectability), and reduced lifetimes ...

Editorial: Metal-Enhanced Fluorescence
Journal of Fluorescence, 2002As fluorescence spectroscopists we are mostly all yields, decreased lifetimes, increased photostability, and familiar with doing spectroscopy in bulk samples, where an increase in Forster transfer distances and directional the solutions are typically transparent to the emitted radia- emission.

DNA hybridization assays using metal-enhanced fluorescence [PDF]
Biochemical and Biophysical Research Communications, 2003 We describe a new approach to DNA hybridization assays using metal-enhanced fluorescence. Thiolated oligonucleotides were bound to silver particles on a glass substrate. Addition of a complementary fluorescein-labeled oligonucleotide resulted in a dramatic time-dependent 12-fold increase in fluorescence intensity during hybridization.

Photodeposition of Silver Can Result in Metal-Enhanced Fluorescence
Applied Spectroscopy, 2003 Chemically deposited silver particles are widely used for surface-enhanced Raman scattering (SERS) and more recently for surface-enhanced fluorescence (SEF), also known as metal-enhanced fluorescence (MEF). We now show that metallic silver deposited by laser illumination results in an ∼7-fold increased intensity of locally bound indocyanine green.

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.
