Non‐invasive exhaled breath diagnostic and monitoring technologies

Abstract

AbstractWith the rapid development of laser technology, information technology, and materials, the detection of trace gas has been taken to a new level. Advanced analytical methods were invented, for example, gas chromatography, mass spectrometry, chemical sensors, absorption spectrum, and so forth. With the detailed data gathered from new high‐tech equipment, we can predict and diagnose diseases such as diabetic ketoacidosis, irritable bowel syndrome, lung cancer and so on. However, there is still a large amount of exhaled gas that has not been discovered, which means that breath analysis of exhaled gas is a very promising field in the future. Non‐invasive breath diagnosis and monitoring technology have attracted huge attention from all over the world. Using exhaled gas to diagnose and monitor human disease has numerous advantages for being non‐invasive, convenient and environment friendly.
