Real-time breath gas analysis

Exploring biomarkers of lung diseases air pollution health effects

There is a clear correlation between air pollution from incomplete combustion of fossil and biomass fuels and prevalent cardiovascular and respiratory diseases, such as chronic obstructive pulmonary disease (COPD). Further investigation of the underlying physiological mechanisms is hampered by the invasive, painful and time consuming nature of existing clinical methods. The aim of the project is to obtain new, fundamental knowledge about the health effects of air pollution by detection of trace gases in exhaled human breath. Breath gas analysis is a rapidly growing area of ​​research for fast and non-invasive detection of biomarkers relevant to medical diagnostics, biomonitoring and toxicology.
