Hebrew University: Finding Fingerprints

Abstract:
Policemen have used fingerprinting techniques for years to find culprits in a variety of criminal cases. Now, Hebrew University of Jerusalem researchers have developed a revolutionary technique that could more quickly and reliably reveal hidden fingerprints, aiding the search for hard-to-detect evidence.

The conventional method uses a gold nanoparticle solution under acidic conditions, a three-part process that produces fingerprint results unstable and difficult to repeat. Professor Daniel Mandler, co-director of the HU Center for Nanoscience and Nanotechnology, professor Joseph Almog, and their team at the Hebrew University have developed a more stable solution by adding hydrocarbon chains to the gold nanoparticles and suspending them in petrol ether. Developed with silver, the prints are of higher quality and can be processed in about three minutes. This new technique is cited in the journal Chemical Communications (March 2007).
