VisEn Medical Inc. of Woburn, Mass., has entered into a joint research program with Eli Lilly and Co. of Indianapolis to find applications for the former company’s fluorescence in vivo imaging technologies in the latter’s research programs. The collaboration should offer VisEn an opportunity to develop products and expand use of its in vivo fluorescence probes, fluorescence molecular tomography and other systems in drug development.
- The emission of light or other electromagnetic radiation of longer wavelengths by a substance as a result of the absorption of some other radiation of shorter wavelengths, provided the emission continues only as long as the stimulus producing it is maintained. In other words, fluorescence is the luminescence that persists for less than about 10-8 s after excitation.
