Complex Biosystems Spectroscopic detection of fluorescent molecules, either those found naturally or those colored with fluorescent dyes, has created new research possibilities for scientists who study proteins and DNA. With photonic instruments like spectrophotometers and spectrofluorimeters, life scientists can measure the low-intensity light emitted from fluorescent molecules. "Because the character of the light emitted from a molecule changes in respect to the environment the molecule is i
