In the air exhaled by humans, there are chemical compounds characteristic of a given disease, the so-called biomarkers. Previous studies have mainly used gas chromatography and mass spectrometry. The difficulty of detecting diseases by means of the above mentioned methods is based on the precise measurement of the amount and type of chemical compounds investigated in the exhaled air. Progress in optoelectronics enables new and alternative possibilities in this field. It is possible to detect disease markers by measuring the absorption of optical radiation at characteristic wavelengths of the wanted biomarkers.

Authors propose applying of ultra-sensitive laser absorption spectroscopy techniques, especially multi-pass cell spectroscopy and cavity ring-down spectroscopy (CRDS). As a part of this project, an optoelectronic sensors system for the detection of volatile disease markers will be developed.
