Abstract:
During the last decades, the potential impact of indoor air quality on human health has stimulated an interest in hazardous compounds survey, such as carbon monoxide (CO). The detection of these compounds has consequently become a vital need. To address this issue, we propose a Surface Acoustic Wave (SAW) device functionalized with metallocorroles used for the selective detection of CO. Here, we insist on the necessity to detect CO in the presence of interferents, such as O2 that is obviously present in the air, carbon dioxide (CO2) present in significant quantity in urban area (400 ppm) and humidity (H2O) which is a well-known interferent in the case of SAW-based gas sensors. Here, we report on the interest of a differential configuration of the sensor that takes advantage of accurate organic layers, to improve the stability of the sensor’s signal and lower the sensitivity to interferents. As an introduction, we provide the context of this study and introduce the two main components of our sensor, which are the SAW device and the metallocorroles.
