Preparation and Thermal Decomposition Kinetics of a New Type of a Magnetic Targeting Drug Carrier

Abstract We have designed a new magnetic targeting drug carrier Fe3O4-PVA with a core of triiron tetroxide (Fe3O4) and a shell made of polyvinyl alcohol (PVA) to improve the hydrophilicity of Fe3O4. With adriamycin hydrochloride as a model drug, this study goes on to measure the drug carrier performance of Fe3O4-PVA. In addition, the thermal stability and enthalpy of thermal decomposition of Fe3O4-PVA were measured using a differential scanning calorimeter with a non-isothermal decomposition method. The kinetics of thermal decomposition of Fe3O4-PVA were also investigated. Over the course of this study, it was determined that the resulting drug carrier Fe3O4-PVA exhibited high drug loading levels and excellent release levels.
