Scaffolds of chitosan/graphene oxide (CS/GO) 0.5% implanted in rat skin; in the images, (A,B) scaffolds are appraised to 4× and 10×, respectively, using the Hematoxylin-Eosin Technique. Images (C,D), at 40×, are scaffolds in the process of degradation and are surrounded by a mixed inflammatory infiltrate. Image (D) is made using Masson’s trichromacy technique; in this image we can see a fibrous tissue capsule surrounding the CS/GO scaffolds. 1: epidermis, 2: Dermis. 3: subcutaneous cellular tissue (implantation zone), 4. Mixed inflammatory infiltrates, 5. Scaffolding CS/GO 0.5%, 6: Fibrous capsule. Technique. Image (A) is at 4× magnification, Image B at 10×. Image (C) at 40×.
