A novel functionalized 3DOM material has been used as supports to immobilize glucose oxidase.Firstly,hybrid 3DOM SiO2-NH2 materials with different amino content were prepared by using(3-aminopropyl)triethoxysilane(APTES) and tetraethoxysilane(TEOS) as precursors and polystyrene colloidal crystal as template.Then,glucose oxidase was immobilized on the pore walls of the 3DOM materials by using glutaric dialdehyde as cross-linking agent.SEM shows that the macropores are highly ordered and interconnected by sma...
