Analysis of initial chlorophyll fluorescence induction kinetics in chloroplasts in terms of rate constants of donor side quenching release and electron trapping in photosystem II [PDF]
The fluorescence induction F(t) of dark-adapted chloroplasts has been studied in multi-turnover 1 s light flashes (MTFs). A theoretical expression for the initial fluorescence rise is derived from a set of rate equations that describes the sequence of ...

Quenching of fluorescence of aromatic molecules by graphene due to electron transfer
Investigations on the fluorescence quenching of graphene have been carried out with two organic donor molecules, pyrene butanaoic acid succinimidyl ester (PyBS, I) and oligo(p-phenylenevinylene) methyl ester (OPV-ester, II).

Anthracene Fluorescence Quenching by a Tetrakis (Ketocarboxamide) Cavitand
Quenching of both fluorescence lifetime and fluorescence intensity of anthracene was investigated in the presence of a newly derived tetrakis (ketocarboxamide) cavitand at various concentrations.

Fluorescence quenching by methylcytosine-metal complexation [PDF]
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.

Aptamer-based cocaine assay using a nanohybrid composed of ZnS/Ag2Se quantum dots, graphene oxide and gold nanoparticles as a fluorescent probe [PDF]
Authors report on a new fluoro-graphene-plasmonic nanohybrid aptamer-based fluorescent nanoprobe for cocaine. To construct the nanoprobe, newly synthesized glutathione-capped ZnS/Ag 2Se quantum dots (QDs) were first conjugated to graphene oxide (GO) to ...
