Sonication-Assisted Metal-Enhanced Fluorescence-Based Bioassays
Analytical Chemistry, 2009A new bioassay technique, sonication-assisted metal-enhanced fluorescence, which is based on the combined use of ultrasound waves and metal-enhanced fluorescence (MEF), is reported. In this technique, low-intensity ultrasound waves significantly reduce the bioassay time by creating a temperature gradient between the bulk and the surface, which is ...

Metal‐Enhanced Fluorescence of CdTe Nanocrystals in Aqueous Solution
ChemPhysChem, 2010AbstractMetal‐enhanced fluorescence of semiconductor nanocrystals (NCs) is investigated. There is very little attention paid to the metal‐enhanced fluorescence in aqueous solution, which has great potential applications in bioscience. In this work, we directly observe metal‐enhanced fluorescence of CdTe NC solution by simply mixing CdTe NCs and Au ...

Review of Advances in Metal-Enhanced Fluorescence
2019In this chapter, we review principles of metal-enhanced fluorescence (MEF), including critical experimental support for the Unified Plasmon-Fluorophore description for the mechanism of MEF. By this description, two routes of enhancement exist for a fluorophore coupled with a metal nanoparticle: namely enhanced absorption and enhanced emission ...

Point-dipole model for metal-enhanced fluorescence
Optics Letters, 2019A simple analytical model for calculating the Purcell factor in metal-enhanced fluorescence (MEF) may replace its difficult precise calculations involving either the Green function of a plasmonic nanoantenna (NA) or the resonator mode volume. The model considers the NA as a point dipole.

Noble-Metal Surfaces for Metal-Enhanced Fluorescence
2004Noble metal nanoparticles exhibit strong absorption bands, which known as the surface plasmon resonances, result in strong absorption and scattering, and create an enhanced local electromagnetic field near-to the surface of the particles. The surface plasmon resonances are highly dependent on the size and the shape of the metal and the dielectric ...
