Increased attention has been focused on development of large-surface-area nanoengineered materials to enhance bone implants performance. Appropriate incorporations of functionalized carbon-based biofilms on the surface of artificial bone tissues can provide improved mechanobiological features. Besides, well-adhered potential coating interfaces corresponding wide spectrum antibacterial targets. Here, a novel morphology of hybrid silver (Ag) nanowall-green reduced graphene oxide (rGO) via facile methodology modified as-sputtered Ag grains to support Ti6Al7Nb implant (Ti67IMP) alloy. Layer-by-layer inorganic-organic topography obtained by physical vapor deposition magnetron sputtering (PVDMS) and subsequent one-step electrochemical deposition (ED) protocols. Microstructure, mechanical and wettability properties were characterized and cytocompatibility of designed composite-Ti67IMP system with human MG-63 osteosarcoma confirmed.
