Comparison of rhodamine 6G, rhodamine B and rhodamine 101 spirolactam based fluorescent probes: A case of pH detection

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2022
Ring-opening reaction of rhodamine spirolactam has been widely applied to construct fluorescent probes. The fluorescence properties of the probe were finely tuned for specific purpose through changing the rhodamine fluorophore. However, the influence on response range and kinetic parameters of the probe during the change has been seldom discussed ...

Sulfone Rhodamines for Voltage Imaging

Chemistry – An Asian Journal, 2022
AbstractFluorescent indicators that respond to changes in biological membrane potentials provide a powerful complement to existing methods for monitoring neuronal activity. Indicators that absorb and emit in the near infrared window are especially attractive, since lower energy wavelengths excite fewer biological molecules and can penetrate more deeply

Acute Exposure to Rhodamine B

Journal of Toxicology: Clinical Toxicology, 1987
Rhodamine B is a red colored dye that is used in cosmetic products. We report a case of 17 patients who were exposed to aerosolized Rhodamine B inside a maintenance shop. The mean duration of exposure was 26 minutes (range 2-65). Sixteen of the patients (94%) complained of acute symptoms including: burning of the eyes (82%), excessive tearing (47 ...

IS RHODAMINE 123 A PHOTOSENSITIZER?

Photochemistry and Photobiology, 1990
Abstract—–Because of conflicting reports on the phototoxicity of rhodamine 123 (Rh 123), we have undertaken a study of Rh 123 photosensitization in severalin vitrosystems. First, Rh 123 is not a photodynamic agent and does not react with singlet oxygen.

Photophysical properties of laser dyes: picosecond laser flash photolysis studies of Rhodamine 6G, Rhodamine B and Rhodamine 101

Journal of the Chemical Society, Faraday Transactions, 1993
The UV–VIS absorptive and emissive properties of three laser dyes, viz. Rhodamine 6G, Rhodamine B and Rhodamine 101, have been studied in ethanolic and methanolic solutions. Time-resolved methods were used to study the decay of the first excited singlet state of each dye.

Photocatalytic activity of ZnO composites against rhodamine B and rhodamine 6G

Fibers and Polymers, 2015
The development of nanostructures based on interaction of organic matrix and metal oxide particles (such as polypyrrole/zinc oxide composites) introduces interesting advantages due to synergistic/complementary photocatalytic activity of resulting material.

Phototoxicity Of Rhodamine Dyes

SPIE Proceedings, 1989
Rhodamine-123 (R123) and tetrabromo-R123 (TBR) have been evaluated in vitro as potential photosensitizers. R123 localizes selectively in mitochondria of MGH-V1 bladder carcinoma cells exposed to 10 pM R123 for 30 min, and under these conditions R123 is a weak photosensitizes.

A new application of Rhodamine 200 B (Sulfo Rhodamine B)

Dyes and Pigments, 1995
Abstract The laser dye Rhodamine 200 B (Sulfo Rhodamine B) (CI Acid Red 52) can be used as a fluorescent counterion for the transfer of various cationic species (e.g. cationic surfactants and crown-complexes of metal ions) into a chloroform phase. The extraction of ionic associates is found to be independent of the acidity of the aqueous phase within

Labeling Mitochondria with Rhodamine 123

Cold Spring Harbor Protocols, 2011
INTRODUCTIONRhodamine 123 is a cationic fluorescent dye that is used to specifically label respiring mitochondria. The dye distributes according to the negative membrane potential across the mitochondrial inner membrane. Loss of potential will result in loss of the dye and, therefore, the fluorescence intensity.
