title: Nucleic-acid-programmed Ag-nanoclusters as a generic platform for visualization of latent fingerprints and exogenous substances.
abstract: We display a nucleic acid controlled AgNC platform for latent fingerprint visualization. The versatile emission of aptamer-modified AgNCs was regulated by the nearby DNA regions. Multi-color images for simultaneous visualization of fingerprints and exogenous components were successfully obtained. A quantitative detection strategy for exogenous substances in fingerprints was also established.
