Abstract:
During the past few decades, Raman spectroscopy has progressed and captivated added attention in the field of science. However, the application of Raman spectroscopy is not limited to the field of forensic science and analytical chemistry; it is one of the emerging spectroscopic techniques, utilized in the field of forensic science which in turn could be a supporting tool in the law and justice system. The advantage of Raman spectroscopy over the other conventional techniques is that it is rapid, reliable, and non-destructive in nature with minimal or no sample preparation. The quantitative and qualitative analysis of evidence from biological and non-biological origins could easily be performed by using Raman spectroscopy. The forensic domain is highly complex with multidisciplinary branches, and therefore a plethora of techniques are utilized for the detection, identification, and differentiation of innumerable pieces of evidence for the purpose of law and justice. Herein, a systematic review is carried out on the application of Raman spectroscopy in the realm of forensic biology and serology considering its usefulness in practical perspectives. This review paper highlights the significance of modern techniques, including micro-Raman spectroscopy, confocal Raman spectroscopy, surface-enhanced Raman spectroscopy, and paper-based surface-enhanced Raman spectroscopy, in the field of Raman spectroscopy. These techniques have demonstrated notable advancements in terms of their applications and capabilities. Furthermore, to comprehensively capture the progress in the development of Raman spectroscopy, all the published papers which could be retrieved from the available databases from the year 2007 to 2022 were incorporated.
摘要:
在过去的几十年里,拉曼光谱在科学领域取得了进展并引起了更多关注。然而,拉曼光谱的应用不仅限于法医学和分析化学领域;它是新兴的光谱技术之一,用于法医学领域,反过来又可以成为法律和司法系统的辅助工具。与其他传统技术相比,拉曼光谱的优势在于它快速,可靠,和非破坏性的性质与最小或没有样品制备。通过使用拉曼光谱,可以轻松地对来自生物和非生物来源的证据进行定量和定性分析。法医领域高度复杂,具有多学科分支,因此,大量的技术被用于检测,identification,为了法律和正义的目的,区分无数的证据。在这里,对拉曼光谱在法医生物学和血清学领域的应用进行了系统的综述,并考虑了其在实际应用中的有用性。这篇综述论文强调了现代技术的意义,包括显微拉曼光谱,共聚焦拉曼光谱,表面增强拉曼光谱,和纸基表面增强拉曼光谱,在拉曼光谱领域。这些技术在其应用和能力方面已经证明了显著的进步。此外,为了全面捕捉拉曼光谱发展的进展,2007年至2022年可从现有数据库中检索到的所有已发表论文均被纳入.
