Chemiluminescence sensors

Chemiluminescence sensors utilize chemicals that generate photons, e.g. 

Here A and B are non-luminescence molecules. The C is the excited state of the product C. Often these reactions involve oxidation reactions and the presence of a catalyst. Both chemical and biochemical reactions could generate the photon. The intensity of the photons are collected through optical fibers and measured with a photon detector. The most successful chemiluminescence sensor for the detection of the hydrogen peroxide [13] is based on luminol using ferricyanide as catalyst...
