a The schematic illustration of the fabrication process on ultrathin GO film by flow-enabled self-assembly and consecutive RGD and AST deposition process. b Biomolecule-functionalized GO sheets using RGD (i) and AST (ii). c The conceptual drawing on the surface-mediated cell functions, enhanced by RGD-integrin interaction (i) and the antioxidant activity of the AST-GO complex (ii). d The possible antioxidant mechanism through the interaction of AST with ROS. e The conceptual image on GO-based patch-type wound dressing. f Transfer printing of the GO/RGD/AST patch directly onto the chicken breast; the inset image in the right panel shows a typical example of maintaining conformal contact of the ultrathin wound dressing under a harsh compression
