Biocompatible reduced graphene oxide prepared by using dextran as a multifunctional reducing agent.
A large-scale, cost-effective, and environmentally friendly synthetic strategy for biocompatible reduced graphene oxide (RGO) by using dextran as a reducing and stabilization agent has been developed. Dextran-coated RGO (D-RGO) was readily soluble in water with high biocompatibility.
