Ultrasonic-assisted preparation of reduced graphene oxide-hydroxyapatite nanocomposite for bone remodeling

An ultrasonic-assisted preparation strategy was employed to synthesize in-situ hydroxyapatite-reduced graphene oxide nanocomposite (n-HA/rGO) as a potential biomaterial for bone regeneration under the osteoporotic condition. The results of Rietveld refinement indicated that the optimum crystallite s...
