Figure Lengend Snippet: A) Schematic illustration of the synthetic process of Pd-RGO nanocomposite. B) Schematic diagram depicting the influence of palladium-reduced graphene oxide (Pd-RGO) nanocomposite on the outgrowth and repair of neurons. The length and complexity of neuronal neurites are enhanced significantly by Pd-RGO nanocomposites substrate that were possibly mediated by increasing of GAP-43, matrix proteins and electrons. C) Schematic diagram of Pd-RGO composites driving neuroprotection against ischemia/reperfusion injury in vivo in rodent model.
