(kem'ē-lū'min-es'ens),
Light produced by chemical action usually at, or below, room temperature.
Synonym(s): chemoluminescence

chemiluminescence

, chemoluminescence (kem?i-loo?mi-nes'ens, kem?o-loo?mi-nes'ens)
Cold light or light resulting from a chemical reaction and without heat production. Certain bacteria, fungi, and fireflies produce this type of light.

chemoluminescence

the emission of light by chemical reactions, most commonly oxidation. (1) Used as a measure of metabolic activity of phagocytic cells, e.g. neutrophils, monocytes and macrophages. (2) A developing technique for marking the state of preservation of food. As the food deteriorates it begins to emit fluorescent light.

The chemoluminescence assay measures the quantity of oxygen radicals produced during granulocyte or macrophage phagocytosis using zymosan as challenge, and the dye luminol as indicator for the achieved grade of oxidation.
Several methods, including reduction of cytochrome c by superoxide ion, luminal chemoluminescence, reduction of scopoletin emission, and electron spin resonance, have been used to measure the generation of ROS induced by asbestos, but such assays are typically-performed in large samples of cells (~[10.
