Surface analysis techniques have rapidly evolved in the last decade. Some of these are already routinely used in forensics, such as for the detection of gunshot residue or for glass analysis. Some surface analysis approaches are attractive for their portability to the crime scene. Others can be very helpful in forensic laboratories owing to their high spatial resolution, analyte coverage, speed, and specificity. Despite this, many proposed applications of the techniques have not yet led to operational deployment. Here, we explore the application of these techniques to the most important traces commonly found in forensic casework. We highlight where there is potential to add value and outline the progress that is needed to achieve operational deployment. We consider within the scope of this review surface mass spectrometry, surface spectroscopy, and surface X-ray spectrometry. We show how these tools show great promise for the analysis of fingerprints, hair, drugs, explosives, and microtraces.
在过去的十年中，表面分析技术得到了迅速发展。其中一些技术已经在法庭科学中得到了常规应用，例如用于检测枪击残留物或用于玻璃分析。一些表面分析方法因其便携性而受到青睐，可以在犯罪现场使用。其他方法由于其具有高空间分辨率、分析物覆盖范围、速度和特异性，因此在法庭科学实验室中非常有帮助。尽管如此，这些技术的许多拟议应用尚未导致实际应用。在这里，我们探讨了这些技术在法庭科学中最常见的痕迹物证中的应用。我们强调了有潜力增加价值的地方，并概述了实现实际应用所需的进展。我们考虑了范围内的表面质谱、表面光谱和表面 X 射线光谱。我们展示了这些工具在分析指纹、头发、毒品、爆炸物和微痕迹方面的巨大潜力。
