The identification and transportation of trace explosive residues following the detonation of an explosive device or during an explosive related criminal investigation is a crucial yet often time consuming process. The ability to detect explosives at or near an explosion scene therefore offers considerable time advantages in the investigation. For this reason, the development of field-deployable portable analytical instruments is an active area of research. This review explores the potential use of electrochemical sensors for in-situ trace explosives detection. A key focus of this review article is the use of room temperature ionic liquids (RTILs) for the electrochemical detection of explosives. The review compares reaction mechanisms for the electrochemical reduction of TNT in aqueous solutions and in RTILs, before a discussion is made on recent work investigating explosives detection in aqueous, non-aqueous and RTIL-based samples. Finally, commentary is made on the anticipated future direction and challenges of this field.

爆炸物电化学检测的最新进展：面向法医学的现场可部署设备

在爆炸装置爆炸之后或在与爆炸物有关的刑事调查期间，识别和运输微量爆炸残留物是至关重要但经常耗时的过程。因此，在爆炸现场或爆炸现场附近检测爆炸物的能力在调查中提供了可观的时间优势。因此，可现场部署的便携式分析仪器的开发是研究的活跃领域。这篇综述探讨了电化学传感器在现场痕量爆炸物检测中的潜在用途。这篇评论文章的重点是使用室温离子液体（RTIL）进行爆炸物的电化学检测。该评论比较了电化学还原TNT在水溶液和RTIL中的反应机理，在讨论有关研究在水基，非水基和基于RTIL的样品中爆炸物检测的最新工作之前，先进行讨论。最后，对该领域的预期未来方向和挑战进行了评论。
