Lab Tests Method To See “Invisible” Fingerprints

Print

Los Alamos National Laboratory is using a new technique to see fingerprints on surfaces that typically make them invisible, the Associated Press. The method uses a technology called mini-X-ray fluorescence to detect chemical elements in fingerprints without altering them, said scientist Christopher Worley.

The technology focuses a tight beam of X-rays on surfaces with fingerprints and creates a computer picture out of those scans. The equipment costs $175,000. The lab is interested in working with New Mexico police agencies to do more tests on the method.
