A Schematic diagram showing the synthesis of graphene-incorporated chitosan nanocomposite substrata. B Quantification of the degree of osteogenesis confirmed by the mineralization as measured by Alizarin Red S staining of hMSCs cultured on the RGO–chitosan substrata, chitosan substrata, and TCPS for 21 days. C Western blot analysis of full length OCN expression and expression of MMP-cleaved OPN in hMSCs cultured on 5% RGO–chitosan substrata, chitosan substrata, and TCPS.
