Chemist contributes to development of novel method for recovering old fingerprints

August 3, 2011


“We’ve been able to successfully target amino acids on non-porous surfaces for the first time, with promising results in enhancing aged and degraded fingermarks that typically give poor results with traditional powdering and cyanoacrylate fuming,” Spindler said. “The potential is there to go back to old cases to see what might now be recovered.”
Hofstetter said. “It’s possible to work on fingerprints of any age or composition and to expand this work further to include other surfaces, possibly even skin.”
Good news if this pans out!
