Abstract
Surface functionalized magnetic iron oxide nanoparticles (NPs) are a kind of novel functional materials, which have been widely used in the biomedical applications such as drug delivery [1]. In order to implement the practical application, the particles must have combined properties of high magnetic saturation, stability, biocompatibility, and interactive functions at the surface. Moreover, the surface of iron oxide NPs could be modified by organic materials or inorganic materials, such as polymers, biomolecules, silica, metals, etc. In this paper  we focused on synthesis of iron nanoparticles and coating of them with PVP,SiO2 and Au to combine drug (theophylline) and apply in drug delivery. The FT-IR, XRD, TEM and SEM and EDX indicated correctly the synthetic nanoparticles and showed drug well loaded on iron oxide nanoparticles surface.
Keywords: Iron oxide nanoparticles, PVP, silica, gold, drug delivery, theophylline
