A fluorescence resonance energy transfer (FRET) platform for the detection of ozone was developed by combining the overlap of the fluorescence spectrum of Ru(bpy)3(2+)-doped silica nanoparticles with the absorption spectrum of indigo carmine at around 600 nm. This FRET system can be used to detect ozone simply within 10 min. Simple qualitative ozone detection methods using cotton swabs or paper...

Various genotoxic textile dyes, xenobiotics, substrates (10 µM) and agrochemicals (100 µg/ml) were tested for enhancement of alkalophilic laccase activity in γ-proteobacterium JB. Neutral Red, Indigo Carmine, Naphthol Base Bordears and Sulphast Ruby dyes increased the activity by 3.7, 2.7, 2.6 and 2.3 fold respectively. Xenobiotics/substrates like p-toluidine, 8-hydroxyquinoline and anthracine ...

Aberrant pancreatic tissue is mostly found in the submucosal layer of the upper gastrointestinal tract, occurring in 1.7% of the population according to summarized post-mortem studies [1]. Gastric pancreatic heterotopia was first recognized by Klob in 1859 [2]. Hereinwe describe the resection of gastric pancreatic heterotopic lesions in children by endoscopic submucosal dissection (ESD). After ...

In this research, the nanosized Fe2V4O13 complex oxide material was synthesized by hydrothermal method. Its structure, morphology characterization, and other properties were determined using X-ray, SEM, EDX, DTA-TG methods. The catalytic activity of evaluated in terms decolorization degradation Indigo carmine dye. optimal condition for reusability catalyst determined. results showed that hetero...

Three new methods are described for the assay of lamivudine in bulk drug and in tablet dosage forms using chloramine-T and two dyes, methyl orange and indigo carmine, as reagents. In titrimetry, aqueous solution of lamivudine is treated with a measured excess of chloramine-T in sulphuric acid medium and after the oxidation of lamivudine is judged to be complete, the unreacted oxidant is determi...
