Abstract

Spherical Janus particles consisting of γ-Fe2O3 and SiO2 bicompartments are effectively prepared through a flame synthetic route. The excellent colloidal stability of these particles offers versatile choices for further manipulating them to form different types of assembled structures. As an example, the synthesis of hollow capsules with a magnetic core and a soft Au/PVP-film shell is demosntrated.
