Fluorophores definition
Did you know?
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. See more • Category:Fluorescent dyes • Fluorescence in the life sciences • Quenching of fluorescence See more Most fluorophores are organic small molecules of 20 - 100 atoms (200 - 1000 Dalton - the molecular weight may be higher depending on grafted modifications, and conjugated molecules), but there are also much larger natural fluorophores that are proteins See more Fluorophore molecules could be either utilized alone, or serve as a fluorescent motif of a functional system. Based on molecular complexity and synthetic methods, … See more Additionally fluorescent dyes find a wide use in industry, going under the name of "neon colours", such as: • Multi … See more • The Database of fluorescent dyes • Table of fluorochromes • The Molecular Probes Handbook - a comprehensive resource for fluorescence technology and its applications. See more WebFluorescence is the emission of a photon of the exact energy separating the excited state at a given configuration, and allows direct relaxation. The utility of fluorescence originates with the difference between the excitation and emission wavelengths.
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.

WebSep 12, 2016 · An important class of photobleaching events are photodynamic, meaning they involve the interaction of the fluorophore with a combination of light and oxygen. Reactions between fluorophores … WebFluorophores can be broadly divided into two main classes—intrinsic and extrinsic. Intrinsic fluorophores are those that occur naturally. These include the aromatic amino acids, NADH, flavins, derivatives of pyridoxyl, and chlorophyll. Extrinsic fluorophores are added to the sample to provide fluorescence when none exists, or to change the ...
