luciferin

(lo͞o-sĭf′ər-ĭn)
n.
A chemical substance present in the cells of bioluminescent organisms, such as fireflies, that produces an almost heatless, bluish-green light when oxidized under the catalytic effects of luciferase and ATP.

luciferin

A class of light-emitting biological pigments that serve as substrate for luciferase (EC 1.13.12.7) in bioluminescence studies.

Sources of luciferin
Firefly, snail, bacteria, coelenterazine, dinoflagellates and deep sea fish (vargulin).

luciferin

a compound which, when acted upon by the enzyme LUCIF ERASE, gives rise to BIOLUMINESCENCE in, for example, fire-flies, glow-worms, some coelenterates and some deep-sea fish.

The PLGA particles gradually release luciferin, which then enters the plant cells, where luciferase performs the chemical reaction that makes luciferin glow.
have tried to prepare nanostructures by caging luciferin and to apply ultrasound to promote the release of caged luciferin [24,25].
Given this efficient production of electronically singlet excited state products, relative nontoxicity of luciferin compounds, and the relatively simple chemistry of these systems, among other beneficial characteristics (as sensitivity and sensibility), several chemi-/bioluminescent systems have gained numerous biomedical, pharmaceutical, and bioanalytical applications.
Fluorescent, protein-based sensors do not require the addition of an exogenous luciferin substrate, and they offer ease of manipulation at the DNA level and subsequent ease of expression in cells and in vivo.
"It was established that the luciferin precursor is also present in non-luminous forest fungi, and more importantly it is about 100 times more abundant than in the biomass of luminous species.
In the phase, the glowworms are initially distributed randomly in the given fitness function space so that they are well dispersed, which have equal quantity of luciferin and sensor range.

FFL(Firefly luciferase) catalyzes the oxidation of luciferin in the presence of ATP, Mg2+ and molecular oxygen to produce light, oxyluciferin, CO2 and AMP [1].
2 Firefly luciferase requires addition of costly substrate luciferin to monitor activity.
The brightness of depends on the luciferin quantity, indicating more pigment means more light.
The majority of them photosynthesize, and like fireflies, they use a light-emitting molecule called luciferin in conjunction with a catalyzing enzyme, luciferase, to produce cold light.
