WebDec 20, 2024 · A fluorophore is a fluorescent molecule that absorbs light at a particular wavelength and then re-emits it when the fluorophore is ""excited."" In most laboratory settings, the fluorophore is chemically (or biologically) added to the sample being studied to identify proteins, antibodies, or amino acids, depending on the kind of fluorophore used. WebSep 1, 2012 · Fluorescence is a process by which a substance absorbs light and then emits light of a different wavelength. In most cases, fluorescing materials emit light of lower frequency and energy than is absorbed, although there are occasionally two-photon emissions in which the emitted light is a higher energy.
