Point of care breath analysis systems

Using sensing tools for detection and classification of breath volatile organic compounds (VOCs) would be cost effective and highly beneficial for the healthcare system, but it still deals with major challenges. Developing accurate diagnostic methods based on the detection of VOCs is an urgent need in the field of medicine. High sensitivity is needed for the discrimination between the VOCs of disease and control patients. Tailoring the VOC sensors toward pre-evaluated VOCs will significantly increase the sensitivity of the diagnostic test. The medical technology seeks miniaturization of medical devices but also aims for a health-screening system of different diseases. In this book, we will review the different arrays of nanomaterial-based sensors for the detection and screening of diseses using VOCs and will discuss the presence of confounding factors as one of the main technological challenge for such sensors.
