Description
Human breath includes many kinds of volatile organic compounds (VOCs). Parts of the VOCs have been regarded as biomarkers of diseases. It has been reported that breath of lung cancer patients includes nonanal whose concentration is ppb level. SnO2-based gas sensors, one of the semiconductor-type sensors, have advantages of simple and real-time monitoring of VOCs-concentration. Conventional SnO2-based gas sensors possess low sensitivity to aldehydes and aliphatic compounds. Therefore, the sensitivity of SnO2-based gas sensors should be improved for detection of ppb-level-nonanal, which consists of aldehyde and saturated methylene chain groups. In this study, we investigate to optimize the amount of noble metal-addition and thickness of films for SnO2-based gas sensors as nonanal sensors.
