Fluorescein is also called "fluorescence" ,it refers to a light emitting cold light phenomenon. When a substance at room temperature by a wavelength of incident light (usually ultraviolet or X-ray) radiation, absorption of light energy into the excited state, and immediately sent back to stimulate and the wavelength of incident light than the length of the outgoing light (wavelength usually visible light).
Fluorescein has been widely used in biochemistry and medicine fields. People can put through a chemical reaction with fluorescent chemical groups bonded to biological macromolecules, and then by observing the emitted fluorescence tracer group to be sensitive to detect these biological macromolecules.
