摘要: 在毒品检测方面，常规实验室检测方法已日趋成熟. 现存的实验室分析方法已不能满足毒品现场快速侦测需求，亟待发展便携式毒品探测技术及设备. 在一些快速检测手段中，便携式设备的应用已经普及并且被不断深入研究. 传感器作为一种具有快速识别目标物质的装置，在毒品检测中可以对一些可疑物品进行快速甄别. 随着毒品种类的变化，以及毒品类型的不断更新迭代，对传感器的检测要求也随之增加，从而不同种类和功能的传感器也应运而生. 鉴于传感器具备易于操作、成本较低、快速分析等特点，在禁毒领域尤其是现场检测方面，便携式毒品传感器的应用会成为现场快速检测的重要组成部分. 近年来，随着人们研究的需求化导向及研究内容的不断深入，一些新型毒品探测技术、材料及设备被成功开发. 随着实测信息的反馈及设备的不断优化，便携式毒品探测设备将成为打击毒品犯罪的有力手段.Abstract: The conventional laboratory detection methods have become increasingly mature in the field of drug detection. The existing laboratory analysis methods can no longer meet the needs of on-site rapid drug detection, and it is urgent to develop portable drug detection technology and equipment. In some rapid detection methods, the application of portable devices has become widespread and is being continuously studied in depth. As a device with rapid identification for target substances, sensors can quickly identify suspicious items in drug detection. With the changes in the types of drugs and the continuous updating and iteration of drug types, the detection requirements for sensors have increased, so that different types and functions of sensors have emerged. In view of the sensor with easy operation, low cost and rapid analysis, the application of portable drug sensors are bound to become an important part of field detection, especially in the field of on-site detection. In recent years, with the demand-oriented research and the deepening of research content, some new drug detection technologies, materials and equipment have been successfully developed. With the feedback of measured information and the continuous optimization of equipment, the portable detection equipment for drugs will become a powerful means to fight against drug crimes.
