Fluorescence and fluorescent dyes [PDF]
Abstract The handling and control of light is becoming more and more attractive in science and technology such as data processing and requires functional chromophores. As a consequence, fluorescent materials are of special importance because they allow the processing of light energy.

On Anomalous Fluorescence of Symmetrical Polymethine Dyes [PDF]
The group-theoretical analysis of polymethine dyes (PMD) showed that relaxation processes between the states S3 and S1 are forbidden, either by radiation or by internal conversion. From the state S3, only transition to the ground state of the molecule is possible. Since the experimental data state that the quantum yield of S3 ⟶ S0 fluorescence does not

Investigating fluorescent dyes in fluorescence-assisted screenings [PDF]
Screening of bead-based peptide libraries against fluorescent dye-labeled target proteins was found to be significantly influenced by the dye characteristics. Commercially available red fluorescent dyes with net negative charges adversely showed strong interactions with library beads.

Taming fluorescent dyes with cucurbituril [PDF]
The potential of the supramolecular host molecule cucurbit[7]uril to serve as a stabilizing additive and enhancement agent was investigated for the following dyes in aqueous solution: rhodamine 6G, rhodamine 123, tetramethylrhodamine, cresyl violet, fluorescein, coumarin 102, pyronin B, pyronin Y, two cyanine 5 and one cyanine 3 derivative, and IR140 ...

CHARMM-DYES: Parameterization of Fluorescent Dyes for Use with the CHARMM Forcefield [PDF]
We present CHARMM-compatible forcefield parameters for a series of fluorescent dyes from the Alexa, Atto and Cy families, commonly used in F¨orster resonance energy transfer (FRET) experiments. These dyes are routinely used in experiments to resolve the dynamics of proteins and nucleic acids at the nanoscale. However, little is known about the accuracy

Cucurbituril Encapsulation of Fluorescent Dyes
The potential of cucurbiturils, water-soluble macrocyclic host molecules composed of glycoluril units, for tuning the properties of fluorescent dyes and advancing new applications is illustrated. Cucurbit[7]uril (CB7), which presents a particularly attractive derivative due to its intermediary size and high water solubility, has been shown to display a

Fluorescence efficiency of laser dyes
The fluorescence efficiency of xanthene dyes, oxazine dyes, and 7-aminocoumarins is discussed. Relations with the molecular structure are pointed out and dependence on solvent and temperature is explained. Several new fluorescence standards are suggested.

Studies on Fluorescent Dyes. II
Syntheses and properties of bistriazinylaminostilbene derivatives have been investigated in order to select excellent fluorescent dyes for practical use. In the synthesic experiment, change of combinations of substitution groups on the triazine ring has been made and the derivatives thus obtained were tested on their solubility, acid-resistant ...

Fluorescent dyes specific for quadruplex DNA [PDF]
Fluorescent dyes which are specific for duplex DNA have found a wide range of applications from staining gels to visualization of chromosomes. Porphyrin dyes have been found which are highly fluorescent in the presence of quadruplex but not duplex DNA. These dyes may offer a route to the specific detection of quadruplex DNA under biologically important

Fluorescent Dye Uptake By Platelets.
SummaryThe uptake of the fluorescent dye euchrysine by human platelets is not affected by the aggregating agents ADP and adrenaline or by endotoxin, but is lost after exposure to anti-platelet and anti-red cell stroma serum. Granules of platelets fail to take up the dye at low temperatures and at an acid pH, both of these conditions being reversible ...
