Exciton interaction in molecular beacons: a sensitive sensor for short range modifications of the nucleic acid structure
Serena Bernacchi,Yves Mély +1 more
TL;DR: It is reported that in the closed form the fluorophore and the quencher form a ground state intramolecular heterodimer whose spectral properties can be described by exciton theory.

Recent advances in the design of small molecule-based FRET sensors for cell biology
TL;DR: The design strategy for the development of small-molecule FRET sensor in terms of avoiding close contact of donor fluorophore and acceptor fluorophores in aqueous solution is described and a strategy to design FRET sensors with a modulating overlap integral of donor andacceptor is introduced.

TL;DR: In this article, multivariate analysis was used to determine the pKa values of Xanthenes derivatives, including eosin Y, erythrosin B and bengal rose B, and also for other synthesized derivatives.

Dye-Capped Gold Nanoclusters: Photoinduced Morphological Changes in Gold/Rhodamine 6G Nanoassemblies
TL;DR: In this paper, a photoinduced morphological changes have been elucidated using picosecond laser flash photolysis, showing that a growth in the particle size (5−20 nm) is observed as a result of melting and fusion of gold nanoparticles, and that adsorption of the cationic dye on the gold surface results in surface charge neutralization causing the Au/dye assembly to aggregate.

Dimerization of Cibacron Blue F3GA and other dyes: influence of salts and temperature
TL;DR: In this paper, the monomer-dimer equilibria of Cibacron Blue F3GA and five other dyes (Levafix Brilliant Blue EB, Reactive Scarlet 017, Methyl Orange, Basic Blue 3 and Chicago Blue Sky) have been investigated in water and in the presence of KH 2 PO 4.

Energy transfer mechanisms and the molecular exciton model for molecular aggregates.
TL;DR: The literature contains numerous experiments designed to demonstrate the presence of excitation energy transfer, and the goal of theseresearches mightwell be not merely the demonstration of the presence, but a more detailed investigation designed to establish which available mechanism of energy transfer is operative.

Quantum yield of singlet oxygen production by xanthene derivatives
TL;DR: In this article, the triplet oxygen quantum yield of 11 purified fluorescein derivatives was determined by reaction with singlet oxygen acceptors in aqueous and ethanolic solutions; in both solvents ϕ1o2 was enhanced with increasing halogenation.
