A method for in situ preparation of fluorescent AuNPs@AuNCs core/shell nanoparticles by the template of BSA coated gold nanoparticles was developed. The as-prepared AuNPs@AuNCs core/shell nanoparticles possessed advantages such as uniform size, improved monodispersity and excellent fluorescence. The AuNPs@AuNCs core/shell nanoparticles in powder and suspension form were applied to the detection of latent fingermark due to the above properties. The developed latent fingermarks by AuNPs@AuNCs core/shell powder on various surfaces can exhibit excellent ridge details with good contrast between the fingermarks and the substrate. Moreover, under alternative light sources, the latent fingermarks developed with AuNPs@AuNCs core/shell powder work well.

Fe3O4nanoparticle was synthesized in the solution involving water and ethanol. Then,α-Fe2O3shell was produced in situ on the surface of theFe3O4nanoparticle by surface oxidation in molten salts, formingα-Fe2O3/Fe3O4core-shell nanostructure. It was showed that the magnetic properties transformed from ferromagnetism to superparamagnetism after the primaryFe3O4nanoparticles were oxidized. Furthermore, the obtainedα-Fe2O3/Fe3O4core-shell nanoparticles were used to photocatalyse solution of methyl orange, and the results revealed thatα-Fe2O3/Fe3O4nanoparticles were more efficient than the self-preparedα-Fe2O3nanoparticles. At the same time, the photocatalyzer was recyclable by applying an appropriate magnetic field.
