Noninvasive Disease Diagnostics: The Swiss Contribution Highlights to Breath Analysis Research

ABSTRACT To celebrate the 125th anniversary of the Swiss Chemical Society, we present a review and perspective to highlight the recent research in breath analysis that has been conducted in Switzerland, with a particular focus on secondary electrospray ionization mass spectrometry (SESI‐HR‐MS). We focus on breath analysis research from 2019, the publication year of the last major review. We highlight where improvements are needed in experimental and clinical protocols and outline the current gaps in the field, to support the implementation of breath analysis into the clinical domain.
