Silica-based mesoporous organic-inorganic hybrid material modified quartz crystal microbalance (QCM) sensors have been examined for their ability to achieve highly sensitive and selective detection. Mesoporous silica SBA-15 serves as an inorganic host with large specific surface area, facilitating gas adsorption, and thus leads to highly sensitive response; while the presence of organic functional groups contributes to the greatly improved specific sensing property. In this work, we summarize our efforts in the rational design and synthesis of novel sensing materials for the detection of hazardous substances, including simulant nerve agent, organic vapor, and heavy metal ion, and develop high-performance QCM-based chemical sensors.
基于二氧化硅的介孔有机-无机杂化材料修饰石英晶体微天平（QCM）传感器已被研究其实现高灵敏度和选择性检测的能力。介孔二氧化硅SBA-15作为具有大比表面积的无机主体，有利于气体吸附，从而导致高灵敏度响应；而有机官能团的存在有助于大大提高特定的传感性能。在这项工作中，我们总结了我们在合理设计和合成用于检测有害物质（包括模拟神经毒剂、有机蒸气和重金属离子）的新型传感材料方面所做的努力，并开发了基于QCM的高性能化学传感器。
