WebThe speed of fluorescence recovery of the bleached area is directly proportional to the diffusion speed of fluorescent or labeled molecules, which gives information about the mobility of the labelled molecules … 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. Such irreversible modifications in covalent bonds are caused by transition from a singlet state to the triplet state of the fluorophores. The number of excitation cycles to achieve full bleaching var…
