Most footwear marks made in blood on a surface such as fabric tend to be enhanced in situ rather than physically recovered using a lifting technique prior to enhancement. This work reports on the use of an alginate material to recover the impressed footwear marks made in blood and deposited on a range of fabric types and colours. The lifted marks were then enhanced using acid black 1 and leuco crystal violet with excellent results. This presents a new method for the lifting and recovery of blood impressions in situ from crime scene followed by subsequent mark enhancement of the lifted impression.
大多数在织物等表面上由血液形成的鞋印往往在原地得到增强，而不是在增强之前使用提取技术进行物理提取。这项工作报告了使用藻酸盐材料提取由血液形成并沉积在一系列织物类型和颜色上的鞋印压痕。然后使用酸性黑1和无色结晶紫对提取的鞋印进行增强，效果极佳。这提出了一种从犯罪现场原地提取和恢复血印，随后对提取的痕迹进行增强的新方法。
