Fluorescence quenching near small metal nanoparticles [PDF]

The Journal of Chemical Physics, 2012
We develop a microscopic model for fluorescence of a molecule (or semiconductor quantum dot) near a small metal nanoparticle. When a molecule is situated close to metal surface, its fluorescence is quenched due to energy transfer to the metal. We perform

Photoluminescence and Fluorescence Quenching of Graphene Oxide: A Review

Nanomaterials, 2022
In recent decades, photoluminescence (PL) material with excellent optical properties has been a hot topic. Graphene oxide (GO) is an excellent candidate for PL material because of its unique optical properties, compared to pure graphene. The existence of

Tryptophan Fluorescence Quenching Assays for Measuring Protein-ligand Binding Affinities: Principles and a Practical Guide

Bio-Protocol, 2019
Tryptophan fluorescence quenching is a type of fluorescence spectroscopy used for binding assays. The assay relies on the ability to quench the intrinsic fluorescence of tryptophan residues within a protein that results from changes in the local ...

Fluorescence Quenching of Aromatic Amino Acids by Rhodium Nanoparticles

Substantia
In this paper, the fluorescence quenching of the aromatic amino acids tyrosine and tryptophan by rhodium nanoparticles has been investigated.The choice of rhodium nanoparticles was determined by the fact that the plasmonic maximum of the nanoparticles ...
