A researcher uses a chemical to extract drug residue from fingerprints Loughborough University
Forensic scientists have developed a new technique that can detect drug and explosive residue on fingerprint samples from crime scenes.
βThat information, the presence of drug particles, is an almost untapped resource,β says at Loughborough University in the UK. That is because investigators use thin gelatine layers, called gel lifters, to lift fingerprints. These introduce chemicals to samples, making it difficult to identify trace amounts of drugs or explosives on them.
