Frequently asked questions about chlorophyll fluorescence, the sequel
(Springer, 2017-04)
Using chlorophyll (Chl) a fluorescence many aspects of the photosynthetic apparatus can be studied, both in vitro and, noninvasively, in vivo. Complementary techniques can help to interpret changes in the Chl a fluorescence ...
The quenching of indolic compounds by monosubstituted benzenes and the photoreaction with chlorobenzene
(Royal Society of Chemistry, 2003-08)
The quenching of the excited singlet of indole and its methyl derivatives by monosubstituted benzenes has been studied in three solvents of different polarities and bimolecular quenching rate constants have been determined. ...
Interaction of a synthetic antimicrobial peptide with model membrane by fluorescence spectroscopy
(Springer, 2013-12-01)
Static and time-resolved fluorescence of tryptophan and ortho-aminobenzoic acid was used to investigate the interaction of the synthetic antimicrobial peptide L1A (IDGLKAIWKKVADLLKNT-NH2) with POPC and POPC:POPG. N-acetylated ...
Luminescence Quenching of Eu(III) Carboxylates by Cu(II) in a Composite Polymer Xerogel Film
(Wiley Blackwell Publishing, Inc, 2006-12)
Three Eu(III) luminescent compounds were separately entrapped in a xerogel porous silica matrix and finely ground particles of it were deposited on a glass support with polyvinylacetate (PVAc) as a binder to build a thin ...
Stress-induced decrement in the plasticity of the physical properties of chick brain membranes
(Taylor & Francis Ltd, 2002-07)
The molecular basis underlying the stress-induced increment in the density of central benzodiazepine receptor from chick forebrain, observed previously at 4°C, was studied from a biophysical perspective. The thermal ...
Diffusion of nitric oxide and oxygen in lipoproteins and membranes studied by pyrene fluorescence quenching
(Society for Redox Biology and Medicine, 2018)
Oxygen and nitric oxide are small hydrophobic molecules that usually need to diffuse a considerable distance to accomplish their biological functions and necessarily need to traverse several lipid membranes. Different ...
Improving arylsulfatase activity determination in dried blood spots: screening and diagnostic approaches for Maroteaux–Lamy syndrome (MPS VI)
(Elsevier, 2015-06)
BACKGROUND: Mucopolysaccharidosis type VI can be screened by measuring the lysosomal arylsulfatase B (ARSB) residual enzyme activity in dried blood spots (DBS) using synthetic substrates. However, we have found experimental ...
Distyrylbenzene-based segmented conjugated polymers: Synthesis, thin film morphology and chemosensing of hydrophobic and hydrophilic nitroaromatics in aqueous media
(Elsevier, 2017-03)
Two new segmented conjugated polymers bearing distyrylbenzene chromophoric units and their model compounds were synthesized. The tendency of the model compounds to form H- and J-type aggregates in the amorphous matrix was ...
Temperature response of luminescent tris(bipyridine)ruthenium(II)-doped silica nanoparticles
(Elsevier Inc, 2013-02)
Nanoparticle-based temperature imaging is an emerging field of advanced applications. Herein, the sensitivity of the phosphorescence of tris(bipyridine)ruthenium(II)-doped silica nanoparticles towards temperature is studied. ...
Quantitative Effects of Pigmentation on the Re‐absorption of Chlorophyll a Fluorescence and Energy Partitioning in leaves
(Wiley Blackwell Publishing, Inc, 2019-11)
This study comparatively examined spectroscopic features, photosynthetic parameters and energy partitioning in plants of Fittonia albivenis cv. Agyroneura and Fittonia albivenis cv. Verschaffeltii with different pigmentation. ...
