Fluorescent Molecules That Can Be Turned On and Off in Aqueous Environments to Visualize Activity Within Cells, University of Miami Study  
8/20/2012 7:43:46 AM

University of Miami scientists have developed a way to switch fluorescent molecules on and off within aqueous environments, by strategically trapping the molecules inside water-soluble particles and controlling them with ultraviolet light. The new system can be used to develop better fluorescent probes for biomedical research. Previous studies have used water-soluble particles to bring organic molecules into water. What is novel about this system is the use of a photoswitching mechanism in combination with these particles.
