Relationships among Graphene, Zinc Oxide and Zinc Oxalate in Nanomedicine

The relationships among graphene (Gr), zinc oxide (ZnO), and zinc oxalate (ZnC2O4) are interpreted from the synthesis perspective. ZnC2O4 can be prepared using the dual-precursor sol-gel method, and can be regarded as the derivative of reduced Gr oxide (rGO) and ZnO. Owing to the wide use of Gr-based materials and ZnO in nanomedicine, it is anticipated that ZnC2O4 can also be used in nanomedicine. The properties of ZnC2O4 (e.g., an open and noncytotoxic structure, solubility, adherence, and affinity) are potentially useful in nanomedicine and are explained in this paper.
