Atto Rho3B NHS ester is a new fluorescent label related to the well-known dye Rhodamine B for coupling to bio-molecules such as DNA, RNA or proteins. The dye shows strong absorption and high thermal and photo-stability. The characteristic feature of the dye is its temperature depending fluorescence yield. The dye is moderately hydrophilic. Atto Rho3B is a cationic dye. After coupling to a substrate the dye carries a net electrical charge of +1.

A flow chemiluminescence (CL) method combined with a liquid-liquid extraction technique is proposed for the indirect determination of antimony in aqueous samples using rhodamine B (RB). In the liquid-liquid extraction process, the antimony(V) chloro-complex anion, [SbCl(6)](-), was extracted from an...

Sequential arrays of chromophores at regulated distances were constructed on a noncovalent DNA molecular assembly system in aqueous media. Photoinduced fluorescence resonance energy transfer (FRET) behaviors were then observed. We designed a number of chromophore/oligo-DNA conjugates with varying sequences. The...

Mitochondria-specific photosensitizers were designed by taking advantage of the preferential localization of delocalized lipophilic cations (DLCs) in mitochondria. Three DLC-porphyrin conjugates: CMP-Rh (a core modified porphyrin-rhodamine B cation), CMP-tPP (a core modified porphyrin-mono-triphenyl phosphonium cation), CMP-(tPP)(2) (a core modified porphyrin-di-tPP...
