Zinc oxide nanostructures for fluorescence and Raman signal enhancement: a review
Beilstein Journal of Nanotechnology, 2022 Since the initial discovery of surface-enhanced Raman scattering (SERS) and surface-enhanced fluorescence (SEF), these techniques have shown huge potential for applications in biomedicine, biotechnology, and optical sensors. Both methods rely on the high

Effect of Silver Nanoparticles on Fluorescence Intensity of Fluoreseina Dye Mixed in One Solution
Iraqi Journal of Physics, 2021 Metal enhanced fluorescence (MEF) is an unequaled phenomenon of metal nanoparticle surface plasmons, when light interacts with the metal nanostructures (silver nanoparticles) which result electromagnetic fields to promote the sensitivity of fluorescence.

Metal-Enhanced Fluorescence (MEF) [PDF]
Biophysical Journal, 2009 In recent years our laboratories have described the favorable interactions and outcomes of both plasmon supporting particles (Ag, Au, Cu, Zn, Ni, Cr) and substrates with electronically excited states. These favorable effects have included enhanced fluorescence emission from singlet states, S1 and S2, as well as enhanced phosphorescence yields from ...

Metal-enhanced fluorescence of single green fluorescent protein (GFP) [PDF]
Biochemical and Biophysical Research Communications, 2008 The green fluorescent protein (GFP) has emerged as a powerful reporter molecule for monitoring gene expression, protein localization, and protein-protein interaction. However, the detection of low concentrations of GFPs is limited by the weakness of the fluorescent signal and the low photostability.

Metal enhanced fluorescence on silicon wafer substrates [PDF]
Chemical Physics Letters, 2008 We report on the fluorescence enhancement induced by silver island film (SIF) deposited on a silicon wafer. The model immunoassay was studied on silvered and unsilvered wafers. The fluorescence brightness of Rhodamine Red X increased about 300% on the SIF, while the lifetime was reduced by several fold and the photostability increased substantially. We

Submicrometer Spatial Resolution of Metal-Enhanced Fluorescence [PDF]
Applied Spectroscopy, 2003 Enhanced fluorescence emission intensity from fluorescein was observed on glass slides covered with thin films of silver nanoparticles using a confocal laser-scanning microscope. The silver nanoparticle film increased the emission intensity of fluorescein by an average of at least three-fold in the area studied.
