Spectral Distortions in Metal-Enhanced Fluorescence [PDF]
In recent years our laboratory and others have demonstrated many examples and concepts in Metal-Enhanced Fluorescence1 (MEF), a surface plasmon phenomenon, which amplifies both fluorescence and luminescence signatures in the near-field, i.e. less than one wavelength of light away from a metallic object1.

Metal-Enhanced Fluorescence-Based RNA Sensing
In this communication, we present the proof-of-principle of a new RNA sensing technique, based on metal-enhanced fluorescence, which may improve the potential of solid substrate-based RNA capture assays. In this regard, the detection of RNA is accomplished by annealing a target RNA tagged with a fluorophore to a DNA anchor probe in a single step on a ...

Metal-enhanced fluorescent biomarkers for cardiac risk assessment [PDF]
In this presentation we describe a novel methodology for ultra-sensitive fluorescence immunoassays based on a new class of fluorescent biomarkers, which are strongly enhanced by nano-size metallic particles. Specifically, we discuss development of the immunoassay on the surfaces coated with metallic particles for high sensitivity detection of cardiac ...
