Schematic demonstration of (A) fabricating graphene derivative nanoparticles (GO, RGO, and AGO), GO was made by chemical oxidation of natural graphite flakes subsequent with Hummers technique, RGO was made from GO by chemical reduction approach (B) fabricating PCL/graphene scaffolds by solvent precipitation approach, and (C) study of stem cell and bacterial response to the substrates for orthopedic applications.
