摘要
针对近年来毒品泛滥,严重威胁社会公共安全的现状,指出违禁物品分析检测技术对涉毒案件的现场排查及物证提取起着至关重要的作用;综述几种典型毒品,如阿片类、可卡因类、苯丙胺类、氯胺酮类等的表面增强拉曼光谱技术检测的进展,分析表面增强拉曼光谱现场、实时检测毒品存在的问题,认为具有灵敏度高、准确性好、操作简单等优越性能的表面增强拉曼光谱技术有望成为最重要的毒品检测手段之一,其未来的发展趋势为:构筑稳健性好的高品质基底,探索新型表面活性剂、稳定剂,开发新型便携式高信噪比拉曼光谱仪,研究泛化性好的智能识别算法。
Abstract
Aim

ing at the status of an increasing spread of illegal drugs which brings severe threats to public security in recent years, it is pointed that technologies of analysis and detection on illicit materials play a vital role in on-site screening and evidence extraction of illegal drugs related events. The application of surface enhanced Raman spectroscopy (SERS) detection in several typical illegal drugs, such as opiates, cocaines, amphetamines, ketamines, and so on, are summarized. Challenges for in-field and real time detection of illegal drugs are analyzed. The SERS is expected to be one of the most popular detection technologies due to its excellent performances, such as sensitivity, accuracy, simple operation, etc. The future development trend of the technology is predicted to be constructing high quality substrate with good robustness, exploring new surfactants and stabilizers, developing a new portable Raman spectrometer with a high signal-noise ratio, and developing intelligent recognition algorithm with good generalization.
