Notes:
Magnetic hydroxyapatite/chitosan nanocomposites were prepared via in situ hybridizationstrategy in the ambient condition. Magnetic hydroxyapatite/chitosan nanocomposites wereinvestigated by XRD, SQUID and TEM. XRD results indicated that the inorganic phases dispersed inchitosan matrix were composed of magnetite and hydroxyapatite. The magnetichydroxyapatite/chitosan shown the behavior of superparamagnetism determined by SQUID, whichindicated the size of magnetite crystal were less than 30nm. The inorganic nanoparticles with size of30-50nm were dispersed chitosan matrix homogeneously. In situ hybridization strategy provided asimple and efficient route to synthesize the magnetic chitosan/hydroxyapatite nanocomposites in themild condition. The most important of in situ hybridization is that the processes of precipitation ofchitosan, synthesis of magnetite and hydroxyapatite, and compositing between three componentswere completed in single step
