【 摘 要 】

Investigation of the interactions between graphene oxide (GO) and biomolecules is very crucialfor the development of biomedical applications based on GO. This study reports the first observation of thespontaneous formation of self-assembled liquid crystals and three-dimensional hydrogels of graphene oxidewith double-stranded DNA by simple mixing in an aqueous buffer media without unwinding double-strandedDNA to single-stranded DNA. The GO/dsDNA hydrogels have shown controlled porosity by changing the concentration of the components. The strong binding between dsDNA and graphene is proved by Ramanspectroscopy
