Unravelling the fluorescence kinetics of light-harvesting proteins with simulated measurements [PDF]
The plant light-harvesting pigment-protein complex LHCII is the major antenna sub-unit of PSII and is generally (though not universally) accepted to play a role in photoprotective energy dissipation under high light conditions, a process known Non-Photochemical Quenching (NPQ).

Fluorescence spectroscopy is one of the most effective methods for studying the binding of drugs to proteins, which is important for the purposes of biochemistry and medicine. When studying the interaction in vitro, human serum albumin (HSA) is used as a

Kinetic models of photosystem II should accommodate the effect of donor side quenching on variable chlorophyll a fluorescence in the microseconds time [PDF]
Quantitative data on laser flash-induced variable fluorescence in the 100 ns to 1 ms time range (Belyaeva et al. in Photosynth Res 98:105–119, 2008) confirming those of others (Steffen et al.

Artificial Receptor in Synthetic Cells Performs Transmembrane Activation of Proteolysis
Transmembrane signaling is the hallmark of living cells and is among the highest challenges for the design of synthetic cells. Herein, an artificial receptor based on the chemistry of self‐immolative linkers is used to communicate information across the lipid bilayer, for transmembrane activation of enzymatic activity. Abstract The design of artificial,

Tunneling induced dark states and controllable fluorescence spectrum in quantum-dot molecules [PDF]
We theoretically investigate the spectrum of the fluorescence from triple quantum-dot molecules and demonstrate that it is possible to use tunneling to induce dark states. Unlike the atomic system, in quantum-dot molecules we can use tunneling to create the dark states and control fluorescence emission, requiring no coupling lasers.

From 2,3-Diazabicyclo[2.2.2]oct-2-ene to Fluorazophore-L, a membrane-bound fluorescent probe for antioxidants [PDF]
The aim of this work was to synthesize and to establish a new fluorescent membrane probe for antioxidants by exploiting the exceptional properties of the long-lived fluorophore 2,3-diazabicyclo[2.2.2]oct-2-ene (DBO) alias Fluorazophore-P.

Positively supercharged mGreenLatern protein is self‐assembled electrostatically with negatively charged zinc phthalocyanines to yield bio‐based photoactive materials in aqueous media. The addition of phthalocyanines results in the formation of large complexes fully quenching of the protein fluorescence. The results indicate an energy transfer from the

The paper explores the creation and characterization of vesicles through biocatalytic Polymerization‐Induced Self‐Assembly (bioPISA), focusing on achieving size uniformity using centrifugation techniques. It examines the effects of stirring speed on vesicle morphology and analyses the internal polymer‐rich structure using fluorescence correlation ...

Hydrogen-Bonding Control of Solvatochromism and Non-Radiative Decay in the Fluorescence of 3-Aminofluoren-9-one Derivatives [PDF]
The object of this study is to determine whether in-plane or out-of-plane hydrogen bonds to solvent molecules more efficiently quench fluorescence in 3-aminofluoren-9-one systems.
