The police and insurance companies only need a careless touch to determine not just the person’s identity, but also their criminal history and definite medical conditions.
Professor David Russell at the University of East Anglia said: "A fingerprint is only good to identify a criminal if you already have their fingerprint on file". Along with Dr. Pompi Hazarika, the two helped each other to develop a new technique that will appear in the German journal. Russell said: "This will give police new tools to help discover that identity".
For decades, scientists have dusted fingerprints using magnetic particles to expose the hidden curls and swirls that distinguish every person on the world. Iron oxide particles connect to the tiny bits of oil, mineral and water that will accumulate on someone’s fingers as they touch any object. The new technique and this iron oxide particles combine with antibodies and suspend both in a liquid solution that is then moistened over a fingerprint. To this point, the scientists can only detect five different drugs, which include methadone, a derivative of methadone, nicotine, cocaine and THC (marijuana). Other drugs, mostly opium-based drugs such as morphine and heroine, should also be noticeable or detectable, since antibodies exist for them to use.
In medical history, drugs are not the only chemical that the new test can detect. Heart failure, cancer, diabetes and other medical conditions can also be detected.
