摘要：

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 rnonodispersity 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.
