A new drug delivery system comprising dopamine-plus-human serum albumin (HSA) modified hollow iron oxide nanoparticles (HIONPs) and doxorubicin (DOX) encapsulated within the hollow porous structure has been developed. The HIONPs每DOX formulation has a pH-dependent drug release behaviour and chemo drug transport and MR imaging of HIONPs每DOX were both obtained.

Monodisperse 10 nm Ni/Pd core/shell nanoparticles with composition control have been synthesized by sequential reduction of nickel(II) acetate and palladium(II) bromide in oleylamine and trioctylphosphine. The as-synthesized Ni/Pd core/shell NPs were supported on graphene and showed high activity, stability and reusability for Suzuki每Miyaura cross-coupling of various aryl halides and phenylboronic acids.
