Dirty Linen: the forensic soft matter science of body fluids on fabric

在许多犯罪现场，体液无处不在。了解它们与各种结构的相互作用对于收集和解释证据至关重要。这个项目几乎肯定是世界上第一个此类项目，目的是探索我们如何应用软物质科学的概念和方法来开始阐明这种相互作用的各个方面，以及这种相互作用如何影响为法医目的保留证据。研究内容的确切性质将与邓迪的法医科学家协商决定，并可以根据学生的技能和兴趣进行定制。一个可能的项目是研究血液如何渗透亚麻，在这个过程结束时各种成分最终在哪里，以及这种吸收如何影响血滴的干燥动力学；但可以想象许多其他的可能性。然而，与广泛的利益相关者(法医科学家、警察、法官等)互动和合作的兴趣……最大限度地发挥工作的潜在影响将是至关重要的。

Body fluids are ubiquitous in many crime scenes. Understanding their interaction with fabric of all kinds is of key importance to the gathering and interpretation of evidence. This project, almost certainly the first of its kind in the world, aims to explore how we may apply the concepts and methods of soft matter science to begin to elucidate aspects of such interaction, and how such interaction affects the retention of evidence for forensic purposes. The precise nature of what is studied will be decided in consultation with forensic scientists at Dundee, and can be tailored to suit the skills and interests of the student. One example of a possible project is to study how blood penetrates linen, where the various components end up at the end of the process, and how such imbibition affects the drying dynamics of blood drops; but many other possibilities can be imagined. However, an interest in interacting and collaborating with a wide range of stake holders (forensic scientists, police, judges, ...) to maximise the potential impact of the work will be essential.
