Providing Fluorescence

Fluorescence which is in biochemistry and medicine has been widely used. 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.
 Fluorescence,is also called as “fluorescence” ,it refers to a photoluminescence phenomenon of cold light. When a substance is under sunshine by at room temperature and a wavelength of incident light (usually ultraviolet or X-ray) radiation, it aborts 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).
