Electronic nose detector smokers

A team at the University of New South Wales in Australia has created an electronic nose that detects smokers quickly and accurately without testing blood or urine.

This nose uses 32 sensors with varying resistance when detecting volatile organic compounds. The results of the tests identified exactly 37 of the 39 volunteers who considered smokers and non-smokers.

The team concludes that electronic noses are capable of detecting fast and accurate smokers without a blood or urine test.

Now, researchers estimate smoking behavior through carbon monoxide exhaling through breath. However, this technique only detects smokers within a few hours after they smoked. The results are also confusing because sometimes carbon monoxide in the breath comes from other sources, such as traffic emissions.

The team also conducted several tests, including the examination of fluid in the body. And the electronic nose can produce accurate results within minutes.

This is very helpful for heart transplant patients because they are not allowed to smoke after surgery. However, a survey in Austria in 2001 found that 15% of heart transplant recipients still sneeze.

"This is just a preliminary study," says a spokesman for the UK Department of Health. "The larger the system, the greater the need for larger, more in-depth trials to demonstrate clinical efficacy. Acceptance of patients.
