Abstract:

Nanomaterials and their characters， synthesis methods and the applications of gold nanoparticle are briefly introduced. Based on the progress of techniques in the field of latent fingerprint development （including original and modified multi-metal deposition method， single metal deposition method， powder method and in situ growth method， etc.）， a review on the visualization of latent fingerprint by gold nanomaterial is presented in details， including the mechanism， advantages and disadvantages of these methods. Combined with the current application of gold nanomaterial in latent fingerprint development， its future progress is also explored.

Key words: gold nanomaterial, latent fingerprint, development, forensic science, review
