Rhodamine B thiolactone is developed as a simple chemosensor towards Hg(2+) in neutral aqueous solution with high selectivity.
A new rhodamine B-based dual-function chromo- and fluorogenic probe for Cu(2+) and ClO(-) has been designed, synthesized, and characterized. The probe comprises a spectroscopic unit of rhodamine B and a Cu(2+)-specific chelating unit of pyridinecarboxamide as well as a ClO(-)-specific reactive moiety of diacylhydrazine, and is a highly selective and extremely sensitive fluorescent and colorimet...
Rhodamine B (RB) is a toxic dye used extensively in textile industry, which must be remediated before its drainage to environment. In the present study, supported gold nanoparticles on commercially available titania and zincite were successfully prepared and then their activity on the photodegradation of RB under UV A light irradiation were evaluated. The synthesized photocatalysts were charact...
New fluorescein and rhodamine B-labeled antifilarial drug DEC analogues for use in drug localization studies with confocal microscopy have been prepared by a high-yield three-step synthesis. The resulting beta-amine-substituted DEC analogue has a single ethyl substituent which is beta-aminated to accommodate the fluorophore of either fluorescein isothiocyananate or rhodamine B. Confocal microsc...
Abstract—The Förster Resonance Energy Transfer (FRET) studies between acridinedione dyes as donors and rhodamine dyes as acceptors are explored by spectroscopic techniques like absorption, fluorescence and lifetime measurements. Enhancement of the acceptor photoluminescence intensity and a decrease of the donor decay time are observed in solutions containing acridinedione dye with Rhodamine B (...
Heterostructured TiO 2 /MoS was prepared via a simple two-step solvothermal approach. The synergistic effect between MoS and illustrated an enhanced adsorption improved performance in the photocatalytic degradation of rhodamine B (99.4%).
A microfluidic channel and a contactless capacitance detector were integrated on a glass chip by a semiconductor manufacturing process for separating and analyzing Rhodamine B and inorganic ion. The electrodes of the capacitance detector were formed successively by sputtering, electroless and electrodepositions. Samples containing fluorescent agent (Rhodamine B) and inorganic ions (K, Na, and L...
In this pepper Fe2O3 nanoparticles were synthesized via a fast microwave method. Then Fe2O3-TiO2 nanocomposites were synthesized by a sonochemical-assisted method. The prepared products were characterized by X-ray diffraction pattern, scanning electron microscopy and Fourier transform infrared spectroscopy. The photocatalytic behaviour of Fe2O3-TiO2 nanocomposites was evaluated using the degrad...
