Scully's research group developed a new approach to detect biochemical molecules using an adapted form of Coherent Anti-Stokes Raman Spectroscopy (CARS) based on enhancing the ground-state molecular coherence, which increases the signal by many orders of magnitude to allow real-time detection of trace amounts of complex molecules. Researchers now can look at the backward-scattered CARS signal to detect chemicals and endospores in real-time with the goal of improving chemical sensing and biomedical imaging.

In the above image, green and red combine together to make purple light in the presence of a trace molecule; no purple indicates that the specific molecule to be detected is not present. (Photo by Michael Kellett.)
