Fabrication of magnetically-functionalized lens- and donut-shaped microparticles by a surface-formation technique.
We report a simple method for the preparation of magnetically-functionalized lens-like and donut-shaped polymeric microparticles, based on spreading a magnetite-doped paraffin-polymer solution at the air/water interface in the presence of an external magnetic field. We examine the parameters that affect the particle morphology and interfacial aggregation behaviour.
