The interaction of small molecules with non-covalent assemblies is of wide interest. The use of a magnetically active reporter nucleus allows information to be obtained in the presence of spectral overlap or in cases of high dynamic range. In this paper, we explore the interaction of a larger probe molecule, 6-fluoro-2-naphthoic acid with assemblies of sunset yellow using (19)F chemical shifts ...

The performance of drug treatment and assessments different drugs' side effects both can be affected by the interaction between food additives drugs. Organic compounds such as colorants dyes are utilized in a wide range foods. In this study, adsorption behavior colorant dye sunset yellow (SY) loratadine was examined. procedure is conducted at dosages, various SY concentrations, temperature (288...

conclusions considering the high level of artificial colors found in the samples of this study, preventive measures are essential. results the results showed that several products did not meet the standards. fifty-six out of the 70 (80%) samples examined in the study, namely sunset yellow (60%), tartrazine (57.1%), quinoline yellow (44.28%), azorubine (28.57%), ponceau 4r (8.57%) and allura red...

The nematic liquid crystal phase is a phase of matter in which the particles have a preferred orientational direction, as opposed to the liquid phase, with no preferred direction, and the solid crystal phase, with an ordered lattice structure. In an aggregated dye, or chromonic, liquid crystal, molecules aggregate together, and the aggregates form a liquid crystal. Aggregated dyes that form liq...

In the present study, nano-scale Zero Valent Iron (NZVI) was synthesized in ethanol medium by the method of ferric iron reduction using sodium borohydride as a reducing agent under atmospheric conditions. The obtained iron nanoparticles are mainly in zero valent oxidation state and remain without significant oxidation for hours. A systematic characterization of NZVI was performed using XRD, SEM...

The dye sunset yellow (SY) forms columnar aggregates via pi-pi stacking in aqueous solutions. These aggregates develop orientational and translational order at elevated concentrations to exhibit the nematic (N) and columnar (C) mesophases. Positional-order correlation lengths of the aggregates in the directions parallel and perpendicular to the stacking direction were measured as functions of t...

BACKGROUND: In this study the possible toxic effects of prolonged administration of three of the widely used food coloring agents are tested. METHODS: Adult female albino rats were administered amaranth (4.7 and 47 mg/kg body weight), sunset yellow (31.5 and 315 mg/kg bwt.) and curcumin (15.75 and 157.5 mg/kg bwt.) at doses equal to and 10 times the acceptable daily intake (ADI). Following whic...

Eleven organic synthetic dyes, currently or formerly used as food colours in Brazil, were tested to determine their effect on mitochondrial respiration in mitochondria isolated from rat liver and kidney. The compounds tested were: Erythrosine, Ponceau 4R, Allura Red, Sunset yellow, Tartrazine, Amaranth, Brilliant Blue, Blue, Fast Red E, Orange GGN and Scarlet GN. All food colours tested inhibit...
