TWO-TONE FLUORESCENCE

Brian Wagner, a chemistry professor at the University of Prince Edward Island, works with fluorescent dyes to develop molecular sensors for pesticides and other analytes. Here, he dissolved the fluorescent molecules perylene (top) and fluorescein (bottom) in the immiscible solvents hexane and water, respectively. Shining ultraviolet light on the solutions reveals two distinctly fluorescing layers.
