Photobleaching 뜻

WebPhotobleaching is the irreversible destruction of a fluorophore under the influence of light. FPbase catalogs efforts that have been made to quantify the photostability of various fluorescent proteins. Typically, these report the time that it takes for the emission intensity of a fluorescent protein to reach half of its initial value, or it may ...

Both the theoretical simulation and experimental data show that photobleaching of fluorescein in microscopy is, in general, not a single-exponential process. The simulation suggests that the non-single-exponential behavior is … 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.
