Review of Chemoselective Reagent Based-Breath Analysis Techniques

Volatile organic compounds (VOCs) pose a threat due to the negative effects of many compounds on human health. VOCs of interest are specific carbonyl compounds produced exogenously and endogenously, resultant of industrial pollution and diseases such as cancer. High concentrations of these carbonyl compounds are found in exhaled breath are linked to cancer, therefore non-invasive breath tests would prove beneficial for cancer diagnosis. Usage of chemoselective cationic reagents allows for efficient testing of these concentrations. The development of these breath tests is detailed in the report
