Abstract

Magnetic nanoparticle Fe304 have super paramagnetic, biological cell compatibility, low toxicity, antibiosis and bacteriostasis, drug loading, sustained release and thermal effect. Using magnetic nanoparticies Fe304 as magnetic source, magnetic masoporous glass two-dimensional bone framework was synthesized under the action of external magnetic field, which provides growth space for bone repair, cell proliferation and metabolism, and contribute to mineralizing. The same time, The application of graphene, especially magnetic nanoparticles Fe304, in bone materials, bone repair and relatedmedicalfields was discussed.

Highlights

  • The lead-in note the ultrapolat material grapheme is divided into power and film [1,2]

  • [12] Magnetic nanoparticles Fe304 was obtained by coprecipitation method, [13,14] hydrothermal method is divided into oilin-water type, and water-in-oil type, which prevents

  • According to different requirements polymer forces are combined to the surface of magnetic nanoparticles Fe304 [15 、 16]
