Fluorescence Quenching of Alpha-Fetoprotein by Gold Nanoparticles: Effect of Dielectric Shell on Non-Radiative Decay

open access: yesNanoscale Research Letters, 2010
Fluorescence quenching spectrometry was applied to study the interactions between gold colloidal nanoparticles and alpha-fetoprotein (AFP). Experimental results show that the gold nanoparticles can quench the fluorescence emission of adsorbed AFP ...

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 in Model Membranes

open access: yesBiophysical Journal, 1982
Fluorescence quenching of membrane-bound fluorophors by nitroxide spin-labeled phospholipids has proved to be a useful technique for examining lipid-fluorophor contact (1-3). When the fluorophor is the tryptophanyl residue of a polypeptide, this method can yield relative binding constants of phospholipids to a membrane-bound polypeptide.

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

open access: yes, 2019
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 ...
