Detect drug use through fingerprints

To know if a person is in a state of 'coffee' drug or not, one must try the urine. However, new inventions can easily detect this just because of fingerprints.

According to Pravda , Paul Yates, working at Intelligent Fingerprinting, is based at Orient English University, and co-workers have devised a pocket-sized device capable of detecting drug-degrading products. through the sweat glands on the fingers .

Equipment coated with gold nanoparticles coated with antibodies on the fingerprint. Antibodies combine with the antigen, corresponding to the metabolite (metabolite) of the individual (ie the person being tested for the drug). Colored fluorescent particles will form by combining antibodies, which will immediately tell whether the person has used the drug.

Thus, the test takes only a few minutes. This device has the ability to accurately detect both nicotine, many other addictive substances such as methadone and those who smoked ... (a ghost, a tree with a family with marijuana).

Author - Mr. Yates said in recent times the identification of the driver caused the accident is due to 'approved' drug or not very complex, often urine analysis under laboratory conditions, Lack of precision when mixed with other biological products. Meanwhile, with the new device, drug metabolites can be detected at the nanogam level for a few minutes.
