Organic dye
WitrynaNational Center for Biotechnology Information WitrynaDyes containing one or more azo groups (i.e. azo dyes) comprise by far the largest family of organic dyes. Prominent types are 1) acid dyes for polyamide and protein substrates such as nylon, wool, and silk; 2) disperse dyes for hydrophobic substrates such as polyester and acetate, and 3) direct and reactive dyes for cellulosic …

WitrynaThe absorption of light in organic cells is done by the ‘dye’ which substitutes for the silicon in conventional cells. This light causes the dye molecules to excite and release … WitrynaAdding multiple acceptor molecules increases the FRET efficiency compared to a single acceptor at the same donor–acceptor distance. 41,42 On the other hand, the larger size of the QD compared to the organic dye increases the donor–acceptor distance, thus decreasing energy transfer efficiency. The interplay between FRET efficiency and …
Witryna11 cze 2024 · Dyes are coloured organic compounds that are used to impart colour to various substrates, including paper, leather, fur, hair, drugs, cosmetics, waxes, greases, plastics and textile materials. A Dye is a coloured compound due to the presence of chromophore and its fixed property to the acid or basic groups such as OH, SO3H, … Witryna2 gru 2024 · Organic dyes offer tremendous diversity of structures, chemical reactivities and spectroscopic properties, which is the great advantage of these fluorescent materials. The dye photostability can create important problems in some applications (discussed in the next section).

Acid dyes are water-soluble anionic dyes that are applied to fibers such as silk, wool, nylon and modified acrylic fibers using neutral to acid dye baths. Attachment to the fiber is attributed, at least partly, to salt formation between anionic groups in the dyes and cationic groups in the fiber. Acid dyes are not substantive to cellul…
Witryna10 sty 2024 · Fluorescein isothiocyanate (FITC) is an organic fluorescent dye and probably one of the most commonly used in immunofluorescence and flow cytometry. It has an excitation/emission peak at 495/517 nm and can be coupled to distinct antibodies with the help of its reactive isothiocyanate group, which is binding to amino, sulfhydryl, …
