| Abstract: | 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 m... |
