An artificial nose developed by researchers at Israel's Ben-Gurion University of the Negev (BGU) can distinguish between different types of bacteria, viruses, and poisonous gases based on their "smell print."

This smell print is produced by the absorption of gases using carbon nanoparticles and the electrical reaction caused by the particles as a result of the absorption.

The researchers said they "were able to 'train' the electronic nose using machine learning techniques to detect different gas molecules, individually or in a mixture, with high accuracy."

BGU's Raz Yelink said the low-cost technology could be used to warn cities about the presence of dangerous gases and air pollution, detect bacterial infections within an hour via a "throat swab" test, and warn of the presence of bacteria in food products.
