Researchers at Princeton University are claiming an extremely sensitive sensor based on Raman scattering that they say opens up new ways to detect a wide range of substances, from tell-tale signs of cancer to hidden explosives.

The sensor is being touted as a major advance in the long-time search to identify materials using Raman scattering, a phenomena discovered in the 1920s by physicist Chandrasekhara Raman where light reflecting off an object carries a signature of its molecular composition and structure.
