Abstract In the present work, surface modification of iron oxide (Fe3O4) nanoparticles with biocompatible fluorapatite (FAP) coating achieved by a simple method and their characterizations using XRD, TEM, FT-IR, DSC and VSM are reported. TEM images revealed the spherical morphology of Fe3O4 nanoparticle and rod-like FAP coated Fe3O4 nanoparticles with size of about 12 and 30 nm, respectively. Magnetic measurements (M-H) of both the samples exhibited superparamagnetic behavior at 300 K. FAP coated Fe3O4 nanoparticles enhance the cell viability and colloidal stability when compared to Fe3O4 nanoparticles. These results demonstrate that FAP coated Fe3O4 nanoparticles could be a suitable candidate for biomedical applications.
