摘要：
In this study, an innovative synthesis process has been developed to produce hydroxyapatite-magnesium ferrite (HA-MgFe2O4) nanocomposite. In addition, the effect of calcination temperature on drug delivery behavior of produced samples was investigated. HA-MgFe2O4 nanocomposite was prepared via one-step modified reverse microemulsion synthesis route. The resulting products were characterized by X-ray Diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), vibrating sample magnetometer (VSM), and Brunauer-Emmett-Teller surface area analysis (BET). The calcined samples at 500 and 700 degrees C demonstrated mesoporous characteristics and large specific surface areas of 88 and 32 m(2)/g, respectively. TEM and VSM results showed that the nanocomposite calcined at 700 degrees C has core-shell morphology and a maximum saturation magnetization of 9.47 emu g(-1). (C) 2016 Elsevier B.V.
