【摘要】 近年来，随着材料学科的蓬勃发展，有关纳米材料的研究也日益增加。粉末显现技术作为现场勘查中最常用的一种手印增强技术，可满足大部分案件需要，但仍然存在一定缺陷，而基于纳米材料的指纹粉末可有效弥补这些缺陷。纳米指纹粉末凭借其吸附性好、独特的荧光特性和选择性强等优势，已逐渐成为手印显现领域的研究热点。综述从物质属性的角度切入，将基于纳米材料的指纹粉末进行科学分类，并详细介绍了目前的研究现状，进一步对纳米粉末在手印显现领域中的研究进行展望。更多还原

【Abstract】 In recent years, with the vigorous development of materials science, the research on nanomaterials is increasing. As one of the most commonly used fingerprint enhancement techniques in field investigation,powder developing technology can meet the needs of most cases, but there are still some defects, and the fingerprint powder based on nanomaterials can effectively make up for these defects. Nanometer fingerprint powder has gradually become a research hotspot in the field of fingerprint development due to its advantages of good adsorption, unique fluorescence characteristics and strong selectivity. This review classifies fingerprint powders based on nanomaterials scientifically from the perspective of material properties, and introduces the current research status in detail, and further prospects the research of nanomaterials in the field of fingerprint development.更多还原
