Fluorophore Definition & Meaning YourDictionary

WebIn optics, photobleaching(sometimes termed fading) is the photochemical alteration of a dye or a fluorophoremolecule 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. WebAug 22, 2024 · Fluorescent labelling is the process of covalently binding fluorescent dyes to biomolecules such as nucleic acids or proteins so that they can be visualized by fluorescence imaging.
