摘　　要：粉末显现法是手印显现技术中被广泛采用的一种传统显现技术,针对不同的客体、环境、手印物质等选择合适的指纹粉末来显现潜在手印,对于刑侦工作具有十分重要的意义。近年来手印遗留客体和手印物质的复杂化、多样化对指纹粉末提出了更高的要求,新型纳米粉末有着比表面积大、吸附性好、稳定性强、可分辨程度高等优势。通过对新型纳米粉末进行分类,并重点阐述其在显现潜在手印领域的应用,同时与传统的粉末显现技术进行比较,旨在为深入推动新型纳米粉末研究提供有价值的参考依据。Powder development is a traditional method widely used in fingerprint development technology to select the appropriate fingerprint powder for revealing latent fingerprints,depending on the type of object,environment,and fingerprint material.It is of great significance for criminal investigation work.In recent years,the complexity and diversity of the objects and fingerprint materials have raised higher requirements for fingerprint powder.New types of nano-powders have advantages such as large surface area,good adsorption,strong stability,and high resolvability.By categorizing the new types of nano-powders and focuses on their application in revealing latent fingerprints,and compares them with traditional powder development techniques,aiming to provide valuable reference for further promoting research on new types of nano-powders.
