Biocompatibility and fabrication of RGO/chitosan film for cartilage tissue recovery.

Graphene oxide (GO) has been successfully deoxygenated via an environmental friendly approach using chitosan. The prepared RGO was characterized using several microscopic and spectroscopic techniques. Also, the synthesized RGO is used to develop a highly compatible film with chitosan. Further, the in-vitro cytotoxicity results showed the biocompatible nature of prepared RGO/chitosan composite towards the human articular chondrocytes indicating their use in future cartilage tissue engineering applications.
