ScienceDaily (May 3, 2008) — Fingerprints that used to escape detection could soon help point to the killer. Using a field portable system being developed by ChemImage and Oak Ridge National Laboratory, investigators at crime scenes will be able to detect latent prints on human skin. The system takes advantage of surface-enhanced Raman spectroscopy (SERS)-based agents to visualize latent prints. A team led by Linda Lewis of ORNL’s Chemical Sciences Division is working with ChemImage to identify fingerprint components that are SERS active, which involves identifying the fingerprint components that give a Raman emission when using a SERS reagent.
