A GRAPHENE-BASED SCAFFOLD FOR HUMAN CELL PROLIFERATION AND A METHOD FOR PRODUCTION THEREOF

摘要

The surface of the L-lysine bonded to graphene oxide and the graphene oxide comprises a suitable composition for human cells, which starts to coat the surface of scafold for human cell culture.Graphene oxide will be replaced by some salts with carboxyl groups.The carboxyl salt may be 4-carboxybenzene diazonium salt.Scafold for human cell culture,The preparation stage of graphene oxide;The graphene oxide was reacted with 4-aminobenzoic acid and sodium nitrate to form graphene oxide benzene disulfate complex;Go-ds-pll composite was formed by the reaction of graphene oxide - benzene disulfate complex with polyamide (PLL);It was fabricated according to the project of spin coating stage on star surface containing the above-mentioned go-dds-pll complex.
