Micro-X-ray fluorescence (MXRF) is a novel technique with the potential to help expand the use of fingerprinting as a forensic investigation tool. Based on the chemical elements present in fingerprint residue, it has an advantage over traditional fingerprint detection methods by adding color to the fingerprint so that it can be easily seen and photographed.Courtesy of Los Alamos National Laboratory.
