Fingerprints to determine whether you have cancer?

According to foreign media reports, British scientists have developed a new technology, through the fingerprint can not only identify a person's identity, but also know the history of drug abuse. The study results were published in Germany, "Applied Chemistry" magazine. Development of this technology the British University of East Anglia, Professor David Russell said that if the police built fingerprints on file, this technology will be provided by the police to discover a good tool for criminals.




Over the years, scientists have used the courts scattered in the fingerprints on the magnetic powder in order to reveal hidden fingerprints unique to each individual vortices and curves. When the iron oxide powder into contact with different objects and other parts of the body when you can attach a little bit of water, minerals and oil in place, which allows fingerprints revealed. This new technology is the iron oxide powder attached to the antibodies on them suspended in the liquid solution, and then sprinkle this solution on the fingerprint. If there is a specific antibody target chemicals, the chemicals would be, and antibody binding, and light.



So far, scientists can identify 5 different drugs: marijuana, cocaine, nicotine, methadone and methadone derivatives. Other drugs, in particular a class of opiate drugs such as heroin and morphine should also be able to detect them, because when they run into the same antibody can play a role. For example, when testing positive for marijuana, this person's fingerprints will be issued green light.



This new drug is not the only technology able to identify chemicals. Cancer, diabetes, heart disease and other diseases can also produce special chemicals, these chemicals are also hidden in the sweat and grease. Take advantage of this technology, scientists will be able to check the court a different health status, which can help the police to track suspects. On the other hand, prosecutors can also use additional fingerprint information to the command of crime. However, the new fingerprint technology and can not be used to monitor the body's health status. It is worth mentioning that this technique can reveal more of the external information, such as whether to have been fired or fried bomb, if the person leaves fingerprints, to track these chemicals can be identified.



Scientists believe that this technology will be employed by the police and even commercialized, because of its much lower cost than magnetic powder.
