Fluorophores definition

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.
