电化学传感器检测环境污染物是实现可持续环境保护和发展的关键策略。传统检测方法依赖独立实验室和复杂操作,且耗时较长,不适宜于快速检测和现场环境监测。因此,迫切需要开发便携、快速、精确的现场检测技术。便携式电化学传感器区别于传统电化学传感器检测的主要特征是不需要实验室繁杂的分析过程和体积较大的检测设备即可实现环境污染物的快速现场检测。智能手机作为广泛使用的日常通讯设备,拥有独立操作系统、内置存储能力和信号传输功能,在现场即时检测(POCT)应用中显示出巨大的潜力。将各种电化学传感与智能手机相结合已经成为便携式电化学传感器领域的一个新发展方向。基于此,从传感模式的角度对近年来基于智能手机的便携式电化学传感器检测环境污染物的研究进展进行了评述,总结了目前基于智能手机的便携式电化学传感器在现场检测环境污染物应用中面临的问题,并对其未来发展前景进行了展望。

The detection of environmental pollutants by electrochemical sensors is a key strategy for achieving sustainable environmental protection and development.Traditional detection methods rely on independent laboratories and complex operations and are time-consuming,making them unsuitable for rapid detection and on-site environmental monitoring.Therefore,there is an urgent need to develop portable,rapid and accurate on-site detection technologies.The main feature of portable electrochemical sensors that distinguishes them from traditional electrochemical sensors is that they do not require complicated laboratory analyses and bulky testing equipment to achieve rapid on-site detection of environmental pollutants.Smart phones,as widely used daily communication devices with independent operating systems,built-in storage capacity and signal transmission capabilities,show great potential for prompt on-site testing(POCT)applications.Combining various electrochemical sensing with smartphones has become a new development direction in the field of portable electrochemical sensors.Based on this,the research progress of smartphone-based portable electrochemical sensors for detecting environmental pollutants in recent years was reviewed from the perspective of sensing modes,and the current problems faced by smartphone-based portable electrochemical sensors in on-site detection of environmental pollutants applications were summarised,with an outlook for their future development.
