摘　　要：在刑事案件尤其是暴力性案件中,需要对现场遗留的血手印进行增强显现,以查明犯罪嫌疑人。其增强显现方法中以化学方法最为常用,而相关化学方法正是基于染料化学相关原理,使用四甲基联苯胺、氨基黑10 B等染料进行着色。本文重点介绍了血手印增强中常用的染料、配方、显现效果以及优缺点,并展望了染料在血手印显现中的应用前景。In criminal cases, especially violent cases, it is necessary to enhance the blood fingermarks left on the scene to identify suspects. Chemical methods are the most commonly used among the enhanced developing methods, and the related chemical methods are based on the related principles of dye chemistry, using dyes such as tetramethylbenzidine and amino black 10 B for coloring. In this paper, the common dyes, formulations, developing effects and advantages and disadvantages in blood fingermarks enhancement are introduced, and the application prospect of dyes in blood fingermark enhancement is forecasted.
