Glowing tags to reveal hidden fingerprints

3 posts in this topic

Scientists have described a new system for visualising "hidden" crime scene fingerprints.

Despite several enhancement techniques already in use, only about 10% of fingerprints from crime scenes are of sufficient quality to be used in court.

The technique is based around fluorescent chemical "tags" and works on metal surfaces, meaning it could be used on knives, guns or bullet casings.
