Fluorescence Studies of the Interplay between Metal-Enhanced Fluorescence and Graphene-Induced Quenching. [PDF]
Materials (Basel), 2018 Fluorescence microscopy and spectroscopy were applied for studying the optical properties of a hybrid nanostructure, in which we combine plasmon-induced metal enhanced fluorescence with energy transfer to epitaxial graphene.

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
