Rhodamine B is a synthetic dye that used to textiles, but it often misused color street food product such as cotton sugar. The short-term effects of Rhodamin if comes in contact with the skin or eyes are irritation affected area, acute poisoning, abdominal pain, vomiting, diarrhea, headaches, dizziness and hypersalivation. While long-term caused gastrointestinal tract, disorders several reprodu...

The effect of the molar concentration Rhodamine B dye on optical absorption spectra and fluorescence spectra. results show that Absorption intensity increased peaks are blue shifted as from 1 to 100 M. In addition, reveal an enhancement absorbance fluorescence quenching is observed. obtained higher than 60µM has come collisional mechanism. Beer-Lambert law governs at low concentrations. While de...

We individuate a photoinduced electron transfer (PeT) as a quenching mechanism affecting rhodamine B photophysics in solvent. The PeT involves an electron transfer from the carboxylate group to the xanthene ring of rhodamine B. This is finely modulated by the subtle balance of coulombic and non-classical interactions between the carboxyphenyl and xanthene rings, also mediated by the solvent. We...

Mucopolysaccharidosis type I (MPS I) is the most common form of the MPS group of genetic diseases. MPS I results from a deficiency in the lysosomal enzyme α-l-iduronidase, leading to accumulation of undegraded heparan and dermatan sulphate glycosaminoglycan (GAG) chains in patient cells. MPS children suffer from multiple organ failure and die in their teens to early twenties. In particular, MPS...
