▎ 摘　　要

As Interface mediated self-assembly of nanocrystals provide excellent strategy for sensing, catalysis or photonics, the construction of innovative interfaces and development of versatile strategies for nanocrystal synthesis are urgently needed. Herein, latent fingerprints (LFPs), the most common markers for human identity, are used as naturally accessible interface for organization of graphene isolated nanocrystals (GINs). Excitingly, the selective adsorption of GINs on lipidic ridge provides a universal approach for the in-situ construction of the plasmonic arrays. Such system with intrinsic chrominance and Raman signal enables the high resolution colorimetric and surfaced-enhanced Raman spectroscopy (SERS) dual-mode imaging, which can detail the structures of the LFPs from 1st to 3rd level even the LFPs are shielded. Furthermore, the interface can be constructed on diverse materials by a simple finger-pressing process and the densely packed arrays can serve as superior SERS substrate for label-free, non-invasive acquisition of molecule information especially residues in LFPs. The combination of chemical composition with detailed structures efficiently recognizes the human identity and could help link it to a crime scene. Overall, the LFPs can act as natural platform for interface mediated localized assembly and personalized information acquisition for forensic science or precise medicine.
