<jats:title>Abstract</jats:title> <jats:p>Positively charged Fe3O4 magnetic nanoparticles were obtained by polyethyleneimine (PEI) as a modification agent. Negatively charged platinum nanoclusters (Pt NCs) were prepared with glutathione (GSH) as reducing agent and protective agent. Finally, spherical fluorescent magnetic nano core-shell microspheres Fe3O4@GSH-Pt NCs were produced through electrostatic adsorption. The magnetic strength was 23.9 emu/g and the fluorescence quantum yield was 8.139%. The experimental results showed that the mean diameter of Fe3O4@GSH-Pt NCs was about 110.3 nm. It emitted red fluorescence at the excitation of 465 nm. Latent fingerprints were directly viewed with excellent ridge details due to the superparamagnetism and excellent fluorescent properties of the prepared Fe3O4@GSH-Pt NCs. Consequently, Fe3O4@GSH-Pt NCs showed great potential in fingerprints detection.</jats:p>
