Abstract
The great demand for antibacterial, biocompatible, and easily manufactured nanostructures has led to the design and development of graphene-wrapped copper nanoparticles (CuNPs) supported on Si wafers. In this study, we investigated the antibacterial properties of graphene/CuNPs nanostructures against Gram-positive and Gram-negative bacteria. Additional experiments regarding graphene/CuNPs nanostructures behavior against mouse fibroblast cell line L929 indicated their biocompatibility and consequently render them as model biomaterials for medical uses. Biofunctionalization of graphene/CuNPs nanostructures with a high-molecular-weight protein (green fluorescent protein), which retains its functionality after a “tight binding” on the nanostructure’s surface, opens the way for attaching and other proteins, or biomolecules of great biological interest, to prepare novel biomaterials.
