The Utility of Green Chemistry in Spectrofluorometric Determination of Ensartinib; An Oncological Drug Using Fluorescamine and Erythrosine B in Pharmaceutical Preparation and Biological Fluid

Sustainable and Sensitive Fluorescence Quenching Spectrofluorometric Approach for Cefixime Determination in Pharmaceutical and Biological Samples

Eco-friendly spectrofluorimetric determination of fenbendazole in pharmaceutical, plasma, and milk samples using erythrosine B as a fluorescent probe

A simple, sensitive, and sustainable spectrofluorimetric method was developed to determine fenbendazole (FEN) based on its fluorescence-quenching interaction with erythrosine B (EB). Under the optimized conditions, FEN efficiently quenched the native fluorescence of EB (λex = 527 nm, λem = 544 nm). The decrease in fluo...

A novel sensitive and validated spectrofluorimetric framework for betrixaban determination in different matrices using erythrosine B–based fluorescence quenching

A novel, sensitive, and eco-friendly spectrofluorimetric approach was developed for quantifying betrixaban. This technique is based on quenching the intrinsic fluorescence of erythrosine B in an acidic Toerell–Stenhagen buffer (pH 4.0). Stern-Volmer analysis confirmed the formation of a non-fluorescent ion-pair complex...

A novel green synchronous spectrofluorimetric platform for ultra-trace simultaneous determination of letrozole and bicalutamide in pharmaceutical, biological, and environmental matrices

A green synchronous spectrofluorimetric method was developed to overcome this limitation by improving spectral resolution through synchronous scanning of the excitation and emission monochromators, and demonstrated satisfactory accuracy, precision, selectivity, and reproducible analytical performance.

Ratiometric fluorescence determination of phoxim in traditional Chinese medicine matrices using Astragalus residue-derived carbon dots and rhodamine B.

An internally referenced fluorescence method was developed for the determination of phoxim in traditional Chinese medicine matrices. Astragalus residue-derived carbon quantum dots (AR-CQDs) were prepared from Astragalus residue and urea by one-step hydrothermal treatment and combined with Rhodamine B (RhB) to form a du...

Ultrafast responsive near-infrared fluorescent probe for the detection of hypochlorous acid and its bioimaging applications in living cells and inflammatory mice.

Hypochlorous acid (HClO), as a key reactive oxygen species (ROS), plays a crucial role in diverse physiopathological processes. Consequently, the development of reliable methods for HClO detection in living systems is of considerable significance. Fluorescent probes with excitation and emission in the near-infrared (NI...
