PARIS – Soon, a machine, as quick and simple as a breathalyzer, could be used to detect COVID-19 from molecules present in exhaled air. The research team from Institut de recherches sur la catalyse et l’environnement de Lyon (IRCELYON – Lyon Institute for Research on Catalysis and the Environment) is investigating the analysis of volatile organic compounds (VOCs) found in exhaled breath for COVID-19 detection.
