摘要
潜在手印是犯罪现场经常出现的一类非常重要的痕迹物证,需要使用一定的显现方法将这类肉眼不可见的手印转变为可见手印.随着手印显现技术的快速发展,相关研究逐渐从法庭科学拓展至多学科交叉领域.近年来,利用电化学方法显现潜在手印的研究引起了研究人员的广泛关注.本文综述了三类基于电化学方法的手印显现技术的国内外研究进展,分别是基于电化学沉积的手印显现技术、基于电化学发光的手印显现技术和基于扫描电化学探针的手印显现技术.最后对这些研究方向的问题现状和发展趋势进行了分析与展望,以期为新型手印显现技术的研究提供有价值的参考.
Latent fingerprints are very important trace evidences that are usually found at crime scenes. Certain development methods are essential to make them visible before the fingerprint identification. With the rapid progress in fingerprint development techniques, related studies gradually expand from forensic science to multidisciplinary fields.In recent years, fingerprint development techniques based on electrochemical methods have attracted great attention. In this paper, research progress in this subject, including the fingerprint development using the electrochemical deposition,electrochemiluminescence and scanning electrochemical microscopy, are reviewed. Meanwhile, the challenges and trends in this field are also analyzed and proposed to provide a useful guidance to researchers.
