隨著奈米材料及質譜成像的快速發展，近來已開始被應用於鑑識科學中之潛伏指紋鑑識。本文先介紹潛伏指紋的化學組成及目前常用顯現技術，說明潛伏指紋鑑識利用奈米材料增強光學影像和質譜儀產生化學影像的操作原理與應用現況。

The rapid development of nanomaterials (NMs) and mass imaging (MI) leads to their applications for forensicidentification of latent fingerprints (LFPs) in forensic science. Herein, we briefly introduce the chemicalcomposition of LFPs and commonly used visualization techniques for LFPs fi rst, followed by demonstrating theoperational principles and current application status of utilizing NMs and MI to enhance visualization extent and togenerate chemical images from LFPs, respectively.
