Fingerprint test tells much more than identityWith a new analytical technique, a fingerprint can reveal much more than the identity of a person. It can also identify what the person has been touching ? drugs, explosives or poisons, for example.
Writing in the Friday issue of the journal Science, R. Graham Cooks, a professor of chemistry at Purdue University, and his colleagues describe how a laboratory technique known as mass spectrometry could find a wider application in crime investigations.
The equipment to perform such tests is already commercially available, although expensive. Smaller, cheaper, portable versions are probably only a couple of years away.
