Fluorescence quenching near small metal nanoparticles [PDF]

open access: greenThe 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 quantum-mechanical calculations of energy transfer rates for nanometer-sized Au nanoparticles and ...

Photoluminescence and Fluorescence Quenching of Graphene Oxide: A Review

open access: yesNanomaterials, 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

Dynamic and static quenching of 2-aminopurine fluorescence by the natural DNA nucleotides in solution

open access: yesMethods and Applications in Fluorescence, 2020
2-aminopurine (2AP) is a responsive fluorescent base analogue that is used widely as a probe of the local molecular environment in DNA. The ability of 2AP to report changes in local conformation and base-stacking interactions arises from the efficient ...

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

open access: yesBio-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 ...

DNA Analysis by Fluorescence Quenching Detection [PDF]

open access: yesGenome Research, 2003
The analysis of human genetic variations such as single nucleotide polymorphisms (SNPs) has great applications in genome-wide association studies of complex genetic traits. We have developed an SNP genotyping method based on the primer extension assay with fluorescence quenching as the detection.

Fluorescence quenching by methylcytosine-metal complexation [PDF]

open access: yesNucleic Acids Symposium Series, 2006
We report the control of fluorescence emission from the fluorophore fixed on DNA using the methylcytosine-selective addition of an osmium(VI)-bipyridine complex. We synthesized the DNA modified by a microenvironment-sensitive fluorophore, 2-dimethylamino-6-acylnaphthalene.

Metal-Induced Fluorescence Quenching of Photoconvertible Fluorescent Protein DendFP

open access: yesMolecules, 2022
Sensitive and accurate detection of specific metal ions is important for sensor development and can advance analytical science and support environmental and human medical examinations. Fluorescent proteins (FPs) can be quenched by specific metal ions and spectroscopically show a unique fluorescence-quenching sensitivity, suggesting their potential ...
