| 中文摘要 | the characteristics of intermediates of bacteriorhodopsin (br) can be verified by chemical modification of its surroundings. ceo2 nanoparticles, which were obtained using water-in-oil (w/o) microemulsion and calcined at various temperatures, were used as chemical additive for the modification of br. x-ray diffraction (xrd) shows that the mean particle sizes for the samples calcined at 500 and 800 degrees c are approximately 10 and 30 nm, respectively. we prepared ceo2 nanoparticle modified poly(vinyl alcohol) (br-pva) films with an optical density of about 1.5 at the ground state. it is observed that the lifetime of the wintermediate for the modified films is prolonged compared with that of the unmodified ones, and the lifetime increases with decreasing particle size. a probable mechanism, which is likely to involve effective molecular interactions between the ceo2 nanoparticles and the br molecules, is discussed. the hydroxyl groups, which might arise from the interaction between the nanoparticles and the surrounding water molecules, help to lower the ability of the schiff base of uptaking protons in the wintermediate. the results indicate that controlling the interactions between biomolecules and various nanomaterials would enlarge the functionality and the range of the application of nanoparticles. |
