摘　　要：血足迹是重大案件中出现的痕迹物证,能够反映出与案件有关的多方面的信息,对于分析案情和检验鉴定具有十分重要的作用,这就使得其显现工作成为现场勘察必不可少的工作。目前国内外显现血足迹的化学试剂主要包括血红素催化试剂、氨基酸显色试剂、蛋白质染色试剂。本文综述了化学试剂显现血足迹的研究进展,并讨论了各化学试剂的适用范围、产物颜色、优劣势,希望能够为公安工作以及血足迹的显现增强提供一定的参考依据。Blood footprints are crucial pieces of physical evidence in major cases,providing multifaceted information related to the incidents,and play an essential role in the case analysis and forensic examinations.Therefore,the visualization of blood footprints has become an indispensable part of crime scene investigations.Currently,the main chemical reagents used both domestically and internationally for revealing blood footprints include heme catalysis agents,amino acid staining reagents,and protein staining reagents.This paper reviews the research progress on chemical reagents for blood footprint visualization and discusses their application scope,the product color,as well as the advantages and disadvantages of each reagent,with the aim of providing valuable insights for law enforcement and improving blood footprint visualization techniques.
