【摘要】：动物的化学感受系统具有惊人的能力,能够在极低的浓度下识别数千种分子结构各异的化学物质,其灵敏性、选择性和响应速度都远高于当前的人工识别系统。近年来,研究者致力于利用完善的天然分子识别机制,开发出一种与传统嗅觉/味觉传感器相比更具仿生意义的新型化学探测系统,即仿生嗅觉/味觉传感器。仿生嗅觉/味觉传感器通常将动物嗅觉味觉的受体、细胞和组织作为敏感材料,然后使用多种人工检测方法,如光学、电化学和声波检测器件等,实现对化学物质的检测和识别。文中概述了动物嗅觉/味觉感受系统对化学物质的信息处理机制,并结合本实验室的工作,综述了目前仿生嗅觉/味觉传感器的常用技术及其未来发展趋势,并展望了其在医疗、工业和军事等领域的应用前景。
[Abstract]:The animal chemosensory system has an amazing ability to recognize thousands of chemicals of different molecular structures at very low concentrations, and their sensitivity, selectivity and response speed are much higher than those of current artificial recognition systems. Researchers are working to develop a new chemical detection system that has more biomimetic significance than traditional olfactory / taste sensors, using perfect natural molecular recognition mechanisms. Bionic olfactory / taste sensors. Bionic olfactory / taste sensors usually use the receptors, cells and tissues of an animal's olfactory taste as sensitive materials, and then use a variety of artificial detection methods, such as optical, electrochemical and acoustic detectors, etc. In this paper, the information processing mechanism of animal olfactory / taste sensing system for chemical substances is summarized, and combined with the work of our laboratory, the detection and recognition of chemical substances are realized. In this paper, the current common technology of bionic olfactory / taste sensor and its future development trend are reviewed, and its application prospect in medical, industrial and military fields is also prospected.
