| azo dye | <chemistry> Dyes that contain the N=N linkage. They are easily prepared from diazo compounds. (18 Nov 1997) |
|---|---|
| azo dyes | Dye's in which the azo group is the chromophore and joins benzene or naphthalene rings; they include a large number of biologic stains, such as Congo red and oil red O; also used clinically to promote epithelial growth in the treatment of ulcers, burns, and other wounds; many have anticoagulant action. (05 Mar 2000) |
| azo- | <chemistry, prefix> A combining form of azote. Applied loosely to compounds having nitrogen variously combined, as in cyanides, nitrates, etc. Now especially applied to compounds containing a two atom nitrogen group uniting two hydrocarbon radicals, as in azobenzene, azobenzoic, etc. These compounds furnish many artificial dyes. See Diazo-. See: Azote. (29 Oct 1998) |

| radiopaque contrast dye | A radiopaque substance (for example metal) will be highlighted (appear white) on a plain X-ray. The use of iodine containing radiopaque contrast dyes allow enhancement of the anatomy demonstrable with conventional X-ray. (27 Sep 1997) |

| Sabin-Feldman dye test | A method for the detection of anti-toxoplasma antibody in serum, based on the fact that Toxoplasma gondii cells (from peritoneal exudate in mice) are fairly well stained with alkaline methylene blue, whereas organisms in a serum that contains specific antibody have no affinity for the dye; furthermore, normal toxoplasma cells become rounded, and the nucleus and cytoplasm deeply stained, when treated with the methylene blue; on the other hand, when dye is mixed with organisms and antibody, the cells retain their crescent shape and only the shrunken nuclear endosome is stained. (05 Mar 2000) |
| salt dye | <technique> A compound of an acid stain and a basic stain, such as the eosinate of methylene blue, in which the anion and cation each contains a chromophore group. Synonym: salt dye. (05 Mar 2000) |
| nitro dye | <chemical> Dye's in which the chromophore is -NO2, which is so acidic that all dyes in this group are of the acid type; important examples in cytoplasmic staining are picric acid and naphthol yellow S. (05 Mar 2000) |
| dye | A stain or colouring matter; a compound consisting of chromophore and auxochrome groups attached to one or more benzene rings, its colour being due to the chromophore and its dyeing affinities to the auxochrome. Dyes are used for intravital colouration of living cells, staining tissues and microorganisms, as antiseptics and germicides, and some as stimulants of epithelial growth. For individual dye's, see the specific names. Commonly but improperly used for radiographic contrast medium. Origin: A.S. Deah, deag (05 Mar 2000) |
| dye-dilution curve | Graph of the serial concentrations (dilutions) of a dye, e.g., Evans blue, following its intravascular or intracardiac injection; useful in the diagnosis of congenital cardiac shunts, measurement of cardiac output, and detection of cardiovalvular incompetence. Synonym: indicator-dilution curve. (05 Mar 2000) |
| dye dilution technique | Method for assessing flow through a system by injection of a known quantity of dye into the system and monitoring its concentration over time at a specific point in the system. (12 Dec 1998) |
| dye exclusion test | A test to determine cell viability in which a dilute solution of certain dyes (e.g., trypan blue, eosin Y, nigrosin, Alcian blue) is mixed with a suspension of live cells; cells that exclude dye are considered to be alive while cells that stain are considered dead; it is not always an accurate test because it indicates only the structural integrity of the cell membrane. (05 Mar 2000) |
| dye laser | <radiobiology> A type of laser in which the active material (the material which emits the laser light) is a dye. These lasers are tunable when the dye has very large molecules (such as acridine red or esculin) and the laser action takes place between the first excited and ground electronic states, because each of these states contains a broad continuum band of vibrational-rotational levels.

| azo dye |
An azo dye is one of an extensive range of synthetic organic dye made from aniline, by first converting it with sodium nitrite to a diazonium chloride salt which is then reacted with other aromatic amines, phenols and sulphonic acids. The well known indicator methyl-orange is formed by making the diazo salt of sulphanilic acid, and reacting the product with dimethylaniline (see below):
