Breath Isoprene Sensor Based on Quartz-Enhanced Photoacoustic Spectroscopy

Sensors
Isoprene, the most abundant endogenous hydrocarbon in human breath, is a promising biomarker for metabolic and cardiovascular diseases. In this paper, we present the detection of isoprene in exhaled breath using the off-beam Quartz-Enhanced Photoacoustic
