Abstract

Detecting trace explosives is crucial for public safety in forensics, security, and environmental monitoring. This review analyzes recent advancements in four key explosive detection technologies: Ion Mobility Spectrometry (IMS), Gas Chromatography-mass spectrometry (GC-MS), Ambient Ionization Mass Spectrometry (AIMS), and Surface-Enhanced Raman Spectroscopy (SERS). IMS excels in detecting low-volatile explosives in complex environments, while GC-MS offers enhanced sensitivity and resolution for trace analysis. AIMS is noted for its rapid, non-invasive, high-throughput capabilities, ideal for real-time detection. Recent improvements in SERS have increased its sensitivity across a broader range of explosive compounds. Despite these advances, challenges such as low recovery rates, cross-sensitivity, and environmental interference remain. The paper highlights the need for continued innovation to improve sensitivity, selectivity, and accuracy, addressing evolving security, forensic, and environmental threats.

爆炸痕迹检测的最新创新：进展和新兴技术

痕量爆炸物的检测在法医、安保和环境监测中对公共安全至关重要。本文综述了离子迁移率光谱法（IMS）、气相色谱-质谱法（GC-MS）、环境电离质谱法（AIMS）和表面增强拉曼光谱法（SERS）四种关键爆炸物检测技术的最新进展。IMS擅长在复杂环境中检测低挥发性爆炸物，而GC-MS为痕量分析提供了更高的灵敏度和分辨率。AIMS以其快速，非侵入性，高通量能力而闻名，是实时检测的理想选择。SERS最近的改进提高了它对更广泛的爆炸性化合物的灵敏度。尽管取得了这些进步，但采收率低、交叉敏感性和环境干扰等挑战仍然存在。本文强调了持续创新的必要性，以提高灵敏度、选择性和准确性，解决不断发展的安全、法医和环境威胁。
