The analysis of body fluid traces during forensic investigations is a critical step in determining the key details of a crime. Several confirmatory and presumptive biochemical tests are currently utilized. However, these tests are all destructive, and no single method can be used to analyze all body fluids. This review outlines recent progress in the development of a novel universal approach for the nondestructive, confirmatory identification of body fluid traces using Raman spectroscopy. The method is based on the use of multidimensional spectroscopic signatures of body fluids and accounts for the intrinsic heterogeneity of dry traces and donor variation. The results presented here demonstrate that Raman spectroscopy has potential for identifying traces of semen, blood, saliva, sweat, and vaginal fluid with high confidence.
在法医学调查中分析体液痕迹是确定犯罪关键细节的关键步骤。目前有几种确证和推定的生化检验方法。然而，这些检验方法都是破坏性的，没有一种单一的方法可以用来分析所有的体液。本综述概述了使用拉曼光谱对体液痕迹进行非破坏性确证鉴定的新型通用方法的最新进展。该方法基于体液多维光谱特征的使用，并考虑了干痕迹和供体变化的固有异质性。这里呈现的结果表明，拉曼光谱法具有高度信心识别精液、血液、唾液、汗液和阴道液痕迹的潜力。
