On-line micellar-enhanced spectrofluorimetric determination of rhodamine dye in cosmetics
(Elsevier Science, 2008-03)
A simple FI-fluorimetric analytical methodology for the continuous and sequential determination of rhodamine B (RhB) in cosmetic products has been developed and evaluated in terms of sensibility and selectivity. The influence ...
Rhodamine spiroamides for multicolor single-molecule switching fluorescent nanoscopy
(Wiley VCH Verlag, 2009-10)
The design, synthesis, and evaluation of new rhodamine spiroamides are described. These molecules have applications in optical nanoscopy based on random switching of the fluorescent single molecules. The new markers may ...
Micelles mediated separation fluorimetric methodology for Rhodamine B determination in condiments, snacks and candies
(Elsevier, 2012-09)
Dye Rhodamine B (RhB) has been widely used in textile industry and foodstuffs but due to its proved carcinogenicity and toxicity on human, many countries have forbidden its use in foods. A new methodology is proposed for ...
Energy transfer from a rhodamine antenna to a ruthenium-bipyridine center
(Royal Society of Chemistry, 2012-05)
The coordination of a modified rhodamine B (Rhod) to a bis-bipyridine ruthenium (ii) (Ru-bpy) phototrigger complex enables a photodissociation reaction at longer wavelengths through enhanced absorption of green light (532 ...
New fluorinated rhodamines for optical microscopy and nanoscopy
(Wiley VCH Verlag, 2010-04)
New photostable rhodamine dyes represented by the compounds 1a-r and 3-5 are proposed as efficient fluorescent markers with unique combination of structural features. Unlike rhodamines with monoalkylated nitrogen atoms, ...
The fluorescence quenching of rhodamine 6G as an alternative sensing strategy for the quantification of silver and gold nanoparticles
(Elsevier Science, 2021-01)
A method for the quantification of 22–26 nm gold (AuNP) and 10–20 nm silver nanoparticles (AgNP) was developed using the fluorescence quenching of rhodamine-6G. This fluorescent probe detected the different metal nanoparticles ...
Photostable, Amino Reactive and Water-Soluble Fluorescent Labels Based on Sulfonated Rhodamine with a Rigidized Xanthene Fragment
(Wiley VCH Verlag, 2008-02)
Highly water soluble fluorescentdyes were synthesized and transformedinto new amino reactive fluorescentlabels for biological microscopy.To this end,rhodamine 8 (preparedfrom 7-hydroxy-1,2,3,4-tetrahydroquinoline(7) and ...
Highly selective and ultrasensitive turn-on luminescence chemosensor for mercury (II) determination based on the rhodamine 6G derivative FC1 and Au nanoparticles
(Molecular Diversity Preservation International, 2016-10)
A method for the detection and quantitation of Hg2+ in aqueous samples by fluorescence spectroscopy is presented. It consists of a turn-on sensor developed by coupling Gold nanoparticles (AuNPs) with the rhodamine 6G ...
Trapping of Rhodamine 6G excitation energy on cellulose microparticles
(Royal Society of Chemistry, 2010)
A ruthenium-rhodamine complex as an activatable fluorescent probe
(American Chemical Society, 2010-07)
We describe the synthesis and characterization of a ruthenium-bipyridyl complex bearing a rhodamine-based fluorescent ligand. The complex is weakly fluorescent due to the quenching of rhodamine. Upon irradiation of the ...
