Representative phase contrast photomicrographs illustrate structural regeneration of spinal cord tissue using a nanoscaffold. The incompletely transected spinal cord is bridged using a reduced graphene oxide scaffold for tissue ingrowth and cell infiltration. (a), Spinal cord adheres well to the nanoscaffold. (b), Loose connective tissue forms between the spinal cord tissue and the reduced graphene oxide scaffold. Bar = 150 μm
