Amsterdam Police Deploy UV-Activated Gunshot Residue Detection in Field Tests

A perovskite-based reagent transforms lead particles into glowing semiconductors, enabling faster and more reliable forensic analysis at crime scenes.

Overview

  • Researchers from AMOLF and the University of Amsterdam developed a method to detect gunshot residue by converting lead particles into UV-activated glowing semiconductors.
  • The technique, now in use by Amsterdam police, is faster, more sensitive, and portable compared to traditional lab-based methods.
  • Field tests confirm the method’s effectiveness, including persistent detection of residue even after extensive hand washing.
  • The reagent also detects lead traces on bystanders and objects at crime scenes, aiding in reconstructing shooting incidents.
  • Developed by the Lumetallix start-up, the technology could expand beyond forensics to monitor environmental lead contamination in water and soil.
