For comparison, the magnetic nanomaterials ( ) were prepared by surface modification. We first report the synthesis and encapsulation of nano-Fe 3O 4 through “facile coprecipitation”, (3-mercaptopropyl)triethoxysilane was covalently embedded into Fe 3O 4 nanoparticles, and the Fe 3O 4 core was encapsulated by the nanosilver to prepare novel magnetic nanomaterials ( ) with the core–shell configuration. As a type of recyclable, environment-friendly material, Fe 3O 4 nanoparticles achieve a wonderful effect in visualization of LFP. Recently, the application of novel nanomaterials, especially magnetic nanomaterials in the development of latent fingerprints (LFP), has become the hot focus for forensic scientists and criminal investigators.
