Glowing tags to reveal hidden fingerprints

Scientists have developed a new way to retrieve a greater number of fingerprints from crime scenes.

Fingerprints are still one of the primary ways in which police investigators are able to identify individuals, even though only around 10% of them are of sufficient quality to be acceptable for use in court. To help improve this figure, police can now use a technique that involves fluorescent chemical "tags" that can be particularly effective at picking up prints on metal surfaces such as knife blades.

"Notwithstanding DNA, fingerprints are still the major source of identification in criminal investigations," said Prof Robert Hillman. "When someone asks: 'Haven't we been doing this for a century, why do we need another method?' Our answer is: 'To image the 90% we don't currently get'."

"The new technique visualises fingerprints by exploiting the fact that their ridges do not conduct electricity."
