Preparation, characterization and properties of core-shell cobalt ferrite/polycaprolactone nanomagnetic biomaterials

Combination of magnetic and biocompatible materials to form core-shell nanomaterials has been widely used in medical fields. These core-shell magnetic biomaterials have a great potential for magnetic fluid hyperthermia (MFH) treatment to remedy cancer. The aims of this study were to investigate the...
