Research progress of graphene and its derivatives in repair of peripheral nerve defect / 中国修复重建外科杂志

ABSTRACT

Objective: To review the research progress of graphene and its derivatives in repair of peripheral nerve defect. Methods: The related literature of graphene and its derivatives in repair of peripheral nerve defect in recent years was extensively reviewed. Results: It is confirmed by in vitro and in vivo experiments that graphene and its derivatives can promote cell adhesion, proliferation, differentiation and neurite growth effectively. They have good electrical conductivity, excellent mechanical properties, larger specific surface area, and other advantages when compared with traditional materials. The three-dimensional scaffold can improve the effect of nerve repair. Conclusion: The metabolic pathways and long-term reaction of graphene and its derivatives in the body are unclear. How to regulate their biodegradation and explain the electric coupling reaction mechanism between cells and materials also need to be further explored.
