Turn On

Rhodamine B thiohydrazide (RBS) was firstly employed as turn-on fluorescent probe for hypochlorite in aqueous solution and living cells. It exhibits a stable response to hypochlorite from 1.0×10-6to 1.0×10-5M with a detection limit of 3.3×10-7M. The response of this probe to hypochlorite is fast and highly selective compared with other reactive oxygen species (such as.OH,1O2, H2O2) and other common anions (such as X-, ClO2-, ClO4-, NO3-, NO2-, OH-, Ac-, CO32-, SO42-).

Tryptophan Metabolite

Synopsis: A well-known tryptophan metabolite, xanthurenic acid, a natural non-fluorescent intermediate siderophore, showed a very selective turn-on response to K+ over other competing metal ions and the detection limit of this natural ionophore was found to be 53 nM at physiological pH.

The adsorption of dye molecules from aqueous solution onto the surface of titanate nanotubes (which have been synthesized via an alkaline hydrothermal treatment) has been studied. The ionic charge on the dye molecules was found to affect their ability to adsorb onto the titanate nanotube surface. In the case of (cationic) methylene blue, the adsorption was preferable on the negatively charged surface of titanate nanotubes rather than on positively charged P25 TiO2 nanoparticles. In the case of (anionic) Eriochrome Black T dye, the opposite trend was found. Herein, the dynamics of dye adsorption and the effect of pH on the adsorption capacity are considered.
