化学传感器由于具有携带方便、灵敏度高、选择性好、易微型化、能用于现场分析和监控等特点而在矿山开发、石油化工、生物医学及日常生活中越来越多地被用来作为易燃、易爆、有毒、有害气体的监测预报和自动控制的装置，或用来测定多种含量极低的物质，甚至可以测量细胞中的离 Chemical sensors are increasingly used in mine development, petrochemicals, biomedicine, and daily life as an easy-to-use, high-sensitivity, high selectivity, easy to miniaturize, and can be used for on-site analysis and monitoring. Fire, explosive, toxic, and hazardous gas monitoring and forecasting and automatic control devices, or used to determine a wide range of extremely low levels of material, even to measure the separation of cells
