“…In addition, the possible risks and threats caused by the storage, transportation, and destruction of the existing sulfur mustard would nonetheless persist due to its characteristics of being volatile and highly diffusible and the lack of an antidote. , To avoid or reduce the potential risk to public safety, developing a low-cost, real-time, and high-sensitivity gas sensor to establish an early warning system is a prerequisite. Given this, various sensors, such as biosensors, fluorescent chemosensors, chemiresistive gas sensors based on nanostructured metal oxides, etc., were suggested for sulfur mustard detection and made great progress. In comparison, metal oxide semiconductor (MOS)-based chemiresistive gas sensors are attractive attention due to their merits of simple preparation, low cost, convenient operation, and miniaturization capability. , In addition, the real-time response and signal transduction properties endow them with prospects to build a sensor network for detection and warning of CWA threats toward a timely countermeasure action.…”
