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 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

In flow metal-enhanced fluorescence for biolabelling and biodetection
Photochemical & Photobiological Sciences, 2020 Escherichia coli bacteria were determined by in flow cytometry with laser excitation and fluorescence detection applying ultraluminescent core-shell nanoparticles based on Metal Enhanced Fluorescence (MEF). Core-shell nanoparticles consisted of a 40 nm core modified with a silica spacer grafted with Rhodamine B (RhB).
