Wavelength-Dependent Metal-Enhanced Fluorescence Biosensors via Resonance Energy Transfer Modulation [PDF]

open access: yesBiosensors, 2023
Fluorescence can be enhanced or quenched depending on the distance between the surface of a metal nanoparticle and the fluorophore molecule. Fluorescence enhancement by nearby metal particles is called metal-enhanced fluorescence (MEF).

Artefact-free Evaluation of Metal Enhanced Fluorescence in Silica Coated Gold Nanoparticles [PDF]

open access: yesScientific Reports, 2017
Metal nanoparticles can either quench or enhance the emission of dyes in their vicinity, but the precise measurement and understanding of this effect is still hindered by experimental artifacts, especially for particles in colloidal dispersion.
