WebSingle Fluorophore Photobleaching, Fig. 1. Jablonski diagram of a fluorophore, showing multiple pathways for photophysical and photochemical processes. Upon excitation, a fluorophore absorbs a photon and jumps to the excited singlet state ( 1 ), from which it can decay to ground state through radiative ( 2) or non-radiative ( 3) pathways.

In optics, photobleaching (sometimes termed fading) is the photochemical alteration of a dye or a fluorophore molecule such that it is permanently unable to fluoresce. This is caused by cleaving of covalent bonds or non-specific reactions between the fluorophore and surrounding molecules.
