Multidimensional Raman Spectroscopic Signatures as a Tool for Forensic Identification of Body Fluid Traces: A Review

Abstract: 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 o… Show more

“…210 The assignment of certain bands to fibrin was later revised 211 as more was learned about the effect of intense laser exposure. 201 After understanding of the chemical heterogeneity of blood spatters increased, Lednev et al proposed that multi-dimensional Raman measurements be attempted, 212 and in 2012 they used the technique to discriminate between dry samples that contained mixtures of human blood and semen. With their multivariate algorithm, mixtures with blood content higher than 80% could not be distinguished from pure blood, while 5% blood in a mixture resulted in a Raman spectrum distinguishable from the spectrum of pure semen 213 (later studies would report on the successful discrimination between dry samples of peripheral blood and menstrual blood, 214 and also between races 215 ).…”

“…[49] It provides specific information on macromolecules, i.e., nucleic acids, proteins, and lipids. [50,51] Their structure, composition, and conformation which is unique to each macromolecule which therefore provides total biochemical state like finger printing of molecule. [52][53][54] Sample preparation is mostly simple and reagent free, and material tested with a Raman can be low as or femtoliters or picograms.…”

“…In outline, the representative Raman spectra of blood, semen, vaginal fluid, saliva and sweat have been proposed as shown in Figure 3, information about their chemical composition has been obtained from the study of their spectral bands and several studies proving the differentiation of these five body fluids based on their characteristic Raman signatures by using chemometrics have been published [33][34][35][36][37][38]. Moreover, multivariate classification models have been developed in order to identify and classify unknown fluids, even in mixtures [39][40][41]. Nevertheless, the stains that were analysed in most of these studies were samples of body fluids on glass slides, not mimicking correctly real crime scene samples.…”

“…For example, a large part of the studies were carried out by analysing samples of body fluids on glass slides or directly placed onto the instrument [25,[33][34][35][36][37][38][39][40][41], which is an extremely unusual substrate in real cases. In addition, studies in which stains were prepared on different clothes such as cotton, polyester, acrylic or wool, exclusively correspond to blood [18][19][20][21][22][23]27,30,31] except for studies [24,26].…”
