The new mini-device was developed by scientists at the company's Intelligent Fingerprinting (Norwich, UK). New "read» fingerprint Analyzing sweat Secreted pores, wherein in case of the presence of drugs in the body, are formed metabolites . Upon detection of metabolites instrument indicates this.
At applying the finger to the device is processed sweat gold nanoparticles coated with antibodies. Whereby, antibodies and certain products of metabolism of drugs in the body bind, and the activation of "attached" to the fluorescent dye antibodies, demonstrating the driver taking narcotic drugs.
Initially, the device was planned to determine the metabolites of nicotine, and later adapted it for the difference of other drugs, not excepting marijuana, cocaine and Methadone .
According to the researcher Paul Yates (Paul Yates), proof of a driver driving a car while intoxicated currently requires a lot of time, because the analyzes conducted suggest blood sampling in a hospital, and it does not exclude contamination of biological samples, and they may not be sufficiently sensitive. With the new device detection nanograms of metabolites It takes a few minutes.
Report this development has already been presented at the International forensic conference in London and looks forward to its approval.
