Abstract
Breath analysis for the identification of volatile organic compounds by mass spectrometry is a very innovative and non-invasive technology, which represents a great opportunity for an early and personalised diagnosis. In this pilot study we recruited a series of volunteers, smokers and non-smokers, characterized from the respiratory point of view, and profiled their exhaled breath through SESI- HRMS technology. The aim of the study is to identify a volatile molecular signature associated with tobacco use. The supervised analysis highlighted 32 features that discriminate the breath of smokers and non-smoker subjects, at the baseline. We therefore identified a volatile molecular signature closely related to tobacco smoke, which will be characterized in subsequent studies.
