基于多肽的气体传感器的研究综述与发展前景

Research review and development prospects of poly peptide-based gas sensors

相比传统的气体传感器,目前多种结构的气体传感器得到了广泛的应用,如有机场效应晶体管(OFET),石英晶体微天平(QCM)等结构。而多肽材料本身具有环境友好、成本低、易修饰等特性,其组装的多肽自组装阵列具有检测限低、易修饰、灵敏度大、特异性较好等优势,被认为是一种理想的敏感材料。因此,在对多肽气体传感器的国内外研究现状进行分析后,阐述了基于多肽的气体传感器的结构设计、工作原理,并对其未来的发展前景进行了展望。

Compared with traditional gas sensors, gas sensors with multiple structures, such as organic field effect transistors(OFET),quartz crystal microbalances(QCM)and other structures have been widely used.The polypeptide material itself has the characteristics of environmental friendliness, low cost, and easy modification.The assembled polypeptide self-assembly array has the advantages of low detection limit, easy modification, high sensitivity, and good specificity.It is considered an ideal sensitive material.Therefore, after analyzing on research status of peptide gas sensors at home and abroad, the structure design, working principle and future development prospects of peptide-based gas sensors are explained.
