The device is made of a series of gold nanoparticles fused to molecules that are very sensitive to volatile organic compounds or VOCs (those released by viruses and infected cells)..
Scientists say that when VOCs interact with molecules on the device, the electrical resistance of the material changes.
With the help of machine learning, they were able to train the sensors on their device to look for COVID-19. They use ML to compare the electrical resistance signal patterns from the breaths of 49 COVID-19-positive patients to 58 healthy individuals and 33 non-COVID lung-infected patients.

They asked the patient to breathe into the device for a few seconds from a distance of 2 centimeters. Whenever the device called someone COVID-19 positive, researchers wrote down the data to test the accuracy of the device.
Researchers found that the device was 76% accurate in finding COVID-19 patients in healthy individuals and 95% accurate in distinguishing people with COVID-19 from people with other types of lung infections.
