Light produced by chemical action usually at, or below, room temperature.
Synonym(s): chemoluminescence


, 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.
See: luciferase


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.
