(a) Schematic drawing of a multifunctional conductive rGO/GelMA engineered hydrogel-based NGC possessing tunable mechanical properties, conductivity, and permeability intended for peripheral nerve regeneration. (b) Photos showing a side view and cross-section of individual nerve conduits with their respective scanning electron micrographs showing inner morphology. (c) In vivo grafting of NGCs into a sciatic nerve defect gap. (d) SFI for various sets at preset time points. (e) Evaluation of electroactivity measurements of compound motor action potential (CMAPs) for different fixed autografts and NGCs. (f) Onset-to-peak amplitude and (g) NCV for each group. (h) Pictures showing muscles and (i) Wet weight ratio of muscles for each group. Reproduced with permission from Ref. [265] copyright © 2020 John Wiley and Sons.
