In luminescent immunoassays like LOCI, the energy that energizes the fluorophore is derived from which type of energy?

Explanation:
In luminescent immunoassays like LOCI, light is produced without an external light source. A chemical reaction releases energy that excites the luminescent system, and the excited state returns to ground state by emitting photons. The signal you detect is light, i.e., radiant energy. So while the energy originates from a chemical reaction (chemical energy), what energizes the fluorophore and becomes observable is radiant energy in the form of emitted photons. This is different from needing external illumination or heat to drive the signal.
