Biomimetic graphene oxide–hydroxyapatite composites via in situ mineralization and hierarchical assembly

A graphene oxide–hydroxyapatite hybrid is synthesized via in situ mineralization. The integrated HAP nanoplates share similar size, morphology and orientations with those of natural bones. With their excellent mechanical properties and biocompatibility, the composites offer potential applications in load-bearing bone repair, scaffold materials and as an alternative model for biomimetic research.
