摘要
Titania thin films with hierarchically macro-mesoporous were prepared by the addition of bulky organic molecule(1,3,5-trimethylbezenze) in aqueous solution of F127(EO106PO70EO106). After calcined at 673 K,ordered thin films with cubic meso-structure and macropores were formed. DNA(Cytochrome c) was used as probe to study the adsorption ability of macromolecules on this film. The hierarchically macro-mesoporous films show high adsorption ability of DNA molecules compared with conventional titania films and mesoporous titania films,which is attributed to the presence of macropores.

The hierarchically macro-meso- porous films show high adsorption ability of DNA molecules compared with conventional titania films and meso- porous titania films, which is attributed to the presence of macropores.
