In response to the increasing demand for precise diagnosis in criminal investigations, magnetic extraction techniques have gained increased attention in forensic analysis. Magnetic extraction is usually based on magnetic materials that could be functionalized to obtain the appropriate functional groups for increasing selectivity and enhancing the analyte recovery. They offer efficient analyte separation and/or enrichment from samples with complex matrices when used in magnetic extraction. This review emphasizes several types of magnetic extraction techniques (including solid phase extraction, stir bar sorptive extraction, liquid phase microextraction, and others) with their evolution in forensic science. It also provides insight into the potential benefits of combining forensic science and magnetic extraction, which will result in superior scientific analysis. The challenges and prospects of developing various magnetic extraction techniques in forensic science are also addressed.

为了满足刑事调查中对精确诊断日益增长的需求，磁提取技术在法医分析中受到越来越多的关注。磁萃取通常基于磁性材料，可以对其进行功能化以获得适当的官能团，从而提高选择性并提高分析物回收率。当用于磁力萃取时，它们可以从具有复杂基质的样品中进行有效的分析物分离和/或富集。本综述强调了几种类型的磁萃取技术（包括固相萃取、搅拌棒吸附萃取、液相微萃取等）及其在法医学中的演变。它还深入了解了法医学和磁力提取相结合的潜在好处，这将带来卓越的科学分析。还讨论了法医学中开发各种磁提取技术的挑战和前景。
