摘要：

The integration of multiple nanoparticles (NPs) with different physical properties into a multifunctional hybrid NP is a challenge. Here, a new wet chemical synthesis is used to generate hybrid NPs by the heterogeneous growth of one NP onto another equivalent-sized NP (see Figure). The hybrid NPs consist of Ag-NPs and Se-NPs in controlled nanoparticle ratios of 1:1, 1:2, and 1:3, respectively. The Se-NPs were grown on the Ag-NP, and the number of Se-NPs was controlled by the initial concentration of Se ions.
