Reaction Mechanism Spectroscopy Studies of Protein and Orange II

open access: yesChemical Engineering Transactions, 2015
In this paper, the interaction of Orange II and Human Serum Albumin was studied by fluorescence spectroscopy under simulated physiological conditions. The affection of pigment and serum albumin may cause changes in the microenvironment.

Unified evaluation of surface-enhanced resonance Raman scattering and fluorescence under strong coupling regime

open access: yes, 2018
We demonstrate importance of molecular multiple excitons and higher-order plasmons for both enhancement and quenching of resonance Raman and fluorescence of single dye molecule located at plasmonic hotspot under strong coupling regime.

Quenching of fluorescence of aromatic molecules by graphene due to electron transfer

open access: yes, 2010
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).

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]

open access: yes, 2008
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 ...

An alternative method for correcting fluorescence quenching [PDF]

open access: yesOcean Science, 2015
Abstract. Under high light intensity, phytoplankton protect their photosystems from bleaching through non-photochemical quenching processes. The consequence of this is suppression of fluorescence emission, which must be corrected when measuring in situ yield with fluorometers. We present data from the Southern Ocean, collected over five austral summers

Fluorescence quenching near small metal nanoparticles

open access: yes, 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
