The quantum yields for singlet oxygen generation of several squarylium cyanine dyes derived from benzothiazole, benzoselenazole and quinoline, displaying absorption within the so-called “phototherapeutic window” (600–1000 nm), were determined, envisioning their potential usefulness for photodynamic therapy (PDT). The determination was performed by a direct method measuring the luminescence deca...
It has been a concern that the cobalt redox cannot give a good performance for the dye-sensitized solar cells when it is used with ruthenium dyes. The electron dynamics measurements clarified the electron loss processes, and clarified the cause. The result indicated the direct interaction between the ruthenium dyes with the cobalt redox, and it reduced the charge injection from the triplet stat...
Here, we present a direct comparison of different dyes and assays for the determination protein concentrations. We compared classical Bradford assay with two modern based on fluorogenic QuDye ProteOrange showed that reagent achieved excellent results in concentrations as more rivals. also standard approaches determining limit detection (LoD) quantification (LoQ) may not work correctly tested dy...
Background and purpose:The presence of dyes in wastewaters may cause serious problems for the environment because of their high toxicity to aquatic organisms and unfavorable aesthetical impact. In the present study, multi-walled carbon nanotubes (MWCNTs) were used for removal of anionic dyes Direct Blue 106 (DB106) and Acid Green 25 (AG25), from water samples. Materials and Methods:MWCNTs were ...
Cellulosic materials like cotton and linen are excellent textile substrates for dyeing with reactive direct dyes. Due to their cellulosic nature, exhibit good affinity towards This is the reason washing rubbing fastness. Chitosan a bio-based polymer gained by deacetylation of chitin. In contrast cellulose, chitosan exhibits also amino functional groups. The purpose this paper evaluate if based ...
