Abstract

Ethyl cellulose porous spheres (ECPSs) loaded with superparamagnetic iron oxide nanoparticles (SPIONs) have been successfully synthesized via a physical method in oil-in-water (O/W) emulsion. The as-prepared ECPSs possess open pores in the shell and interconnected pores inside the spheres by means of phase separation. The SPIONs with an average size of around 5 nm synthesized by co-precipitation method are added into oil phase precursor in the preparation of ECPSs to synthesize the ECPSs-SPIONs. The loading of SPIONs does not change the morphology of ECPSs, while endows the ECPSs with high ferromagnetic properties at room temperature. The resultant ECPSs-SPIONs can be easily separated from dispersion liquid or driven to specific sites under an external magnet.
