Inventing 'electronic nose' to detect explosives and drugs

Russian engineers from the National Nuclear Research University have invented 'electronic nose'. This device can detect explosives and drugs or find survivors under the rubble. Professor of National Nuclear Research University Nikolai Samotaev said:

"The electronic nose works on a spectral basis. This compact handheld device is like a nose tube. It can identify thousands of different chemicals."

However, the question is why it is necessary to invent sophisticated electronic devices when there is something similar created by nature itself such as a dog. 200 million olfactory cells in the dog's nose can detect some molecules of the substance in the air. But the hound is not the perfect assistant. Nikolai Samotaev said:

'How is training a dog? People forced dogs to sniff out explosives and let them eat good prey. It will remember that and then will find the correct explosives. But very difficult to adjust a dog. Meanwhile our machine is programmed to find many different smells. "

In addition to explosives, the device can detect drugs in small doses, can even identify people. Every person radiates a distinct smell of lactic acid. Mr. Nikolay Samotaev continued:

"If a person is buried under a pile of dumps, the body odor will accumulate in a confined space. This odor escapes from the cracks formed in the rubble. If the alarm device has lactic acid present , that is, there are people under the rubble. "

But this device was built not for people. Its original task is to monitor the situation of nuclear power plants. That is why the device relates to the National Nuclear Research University. But scientists have discovered that the device is extremely sensitive, its analysis is useful, especially for doctors. Associate Professor Nicholas Samotaev continued:

"The Japanese side is very interested in our equipment. There is a high risk of bird flu epidemic over there. People from other places come without weapons, but check their body temperature through machines. Fever is screened to detect acute infectious disease Our equipment also allows rapid diagnosis of diseases such as bird flu, septicemia, tuberculosis ".

In short, in the future, the work of doctors will have serious changes. Shooting jealous, expensive and expensive electric projectors will belong to the past.
