➀ Researchers at Saarland University are developing a non-invasive diagnostic method to detect diseases such as cystic fibrosis and Covid-19 by analyzing odor patterns. ➁ The research aims to identify unique scent profiles for various infections, similar to fingerprints. ➂ The team is working on collecting volatile organic compounds from breath, saliva, sputum, and sweat to create diagnostic tools that could be used in clinical settings for early detection of infections.
