Photobleaching fluorescence microscopy
WebPhotobleaching - Java Tutorial. The phenomenon of photobleaching (also commonly referred to as fading) occurs when a fluorophore permanently loses the ability to fluoresce due to photon-induced chemical damage and covalent modification.Upon transition from an excited singlet state to the excited triplet state, fluorophores may interact with another … WebHigh-intensity illumination can cause the fluorophore to change its structure so that it can no longer fluoresce—this is called photobleaching. Photobleaching process. (A) Fluorescence occurs in repeated cycle. (B) Molecule is structurally unstable and begins to fall apart during the excitation state. (C) Molecule’s ability to fluoresce is ...
