WebDefinition. Photobleaching describes any process that leads to the permanent loss of fluorescence from light-emitting fluorescent species, including organic dye molecules, semiconductor particles such as quantum dots, and fluorescent proteins. As such processes terminate the flux of photons emanating from a fluorophore, photobleaching serves as ... WebMar 9, 2024 · Skin optical inspection is an imperative procedure for a suspicious dermal lesion since very early skin cancer detection can guarantee total recovery. Dermoscopy, confocal laser scanning microscopy, optical coherence tomography, multispectral imaging, multiphoton laser imaging, and 3D topography are the most outstanding optical …
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.
A fluorophore (or fluorochrome, similarly to a chromophore) is a fluorescent chemical compound that can re-emit light upon light excitation. Fluorophores typically contain several combined aromatic groups, or planar or cyclic molecules with several π bonds. Fluorophores are sometimes used alone, as a … See more The fluorophore absorbs light energy of a specific wavelength and re-emits light at a longer wavelength. The absorbed wavelengths, energy transfer efficiency, and time before emission depend on both the fluorophore … See more Fluorophores have particular importance in the field of biochemistry and protein studies, e.g., in immunofluorescence but also in cell analysis, e.g. immunohistochemistry and small molecule sensors.
