Abstract

To mix or not to mix: Integrated (left) and segregated (right) assemblies were obtained upon treating functionalized γ-Fe2O3 nanoparticles (NPs) with AuNPs. Their binary nature is controlled by the capping layer of the γ-Fe2O3 NPs and the AuNP initial aggregation state. The segregated assembly formation is induced by AuNP aggregates which act as nucleation sites for growth of the γ-Fe 2O3 NP domains.
