(a) Schematic representation of rolling up protocol for nerve guide conduit (NGC) containing SF/SWNT/FN. (1) Porous SF/SWNT substrates. (2) Aligned FN containing nanofibers prepared by electrospinning on substrate. (3) Rolling up the complex. (4) Tubular NGC with internal aligned nanofibers coated by porous Silk/SWNT substrate. (b) Implanted SF/SWNT/FN. conduit in left sciatic nerve defects in a rat model after 5 weeks implantation. (c) Cross sections of regenerated nerves taken from SF/SWNT/FN nerve conduit after 5 weeks. Wide arrows: myelinated axon. Narrow arrows: Schwann cells (adapted from reference [59]).
