Electronic nose, a wonderful device to detect life threatening diseases….

 A new way of testing e-nose: 'nose' that smells diseases, with this electronic nose, diseases like liver, lung and colon cancer will be able to detect. 

Scientists are developing new types of tests to identify diseases. An electronic nose or e-nose is the best example of this type of modern test. Diseases like liver, lung, and colon cancer can be detected through electronic noses. 

To check for diseases, this nose has to be applied like a mask on your nose and the disease will be detected within a few seconds.UK Biotech company Oulstone Medical, who prepared it, says that work is also being done to detect Covid with the help of an electronic nose (e-nose).  

According to the research, usually, the patient does not feel comfortable while giving blood, urine, and stool samples, but the new test will prove to be very easy for the patients and will also take very least time. 

Now the question is how Electronic Nose Works? 

This e-nose detects the disease by detecting the smell of disease coming from the patient's breath. Scientists say that when humans exhale, there are more than 3500 Volatile Organic Compounds (VOCs) in it. It consists of extremely small gas particles and microscopic droplets. E-nose detects chemicals present in volatile organic compounds and thus detects diseases. 

It took 51 years to make the device. The idea of ​​​​creating it came to scientists in 1970 itself, but it took decades to convert this idea into a sensitive device, programming to recognize volatile organic compounds, and creating sensors. Its trial is going on in many countries around the world. The results, especially in the UK, have been impressive. 

Experts say, in the next five years, the test done through e-nose will become like a routine test. Continuous work is being done on this. Scientists say it is being tried that the device can also tell which medicine will be better for the patient according to the disease. 

Using the same technology for cancer screening-

Through this technique, clinical trials related to breathing are going on in many countries around the world. It also includes trials related to cancer. The goal of the trial is to detect cancer early. The trial is being conducted on 4000 patients in UK hospitals in collaboration with Cambridge University and the NHS Foundation.
