| 中文摘要 | the immobilization of surface-derivatized gold nanoparticles onto methyl-terminated self-assembled monolayers (sams) on gold surface was achieved by the cooperation of hydrophobic and electrophoretic forces. electrochemical and scanning probe microscopy techniques were utilized to explore the influence of the sam's structure and properties of the nanoparticle/sam/gold system. sams prepared from 1-decanethiol (dt) and 2-mercapto-3-n-octylthiophene (mot) were used as hydrophobic substrates. the dt sam is a closely packed and organized monolayer, which can effectively block the underlying gold and inhibit a variety of solution species including organic and inorganic molecules from penetrating, whereas the mot monolayer is poorly packed or disorganized (because of a large difference in dimension between the thiophene head and the alkylchain tail) and permeable to many organic probes in aqueous solution but not to inorganic probes. thus, the mot monolayer provides a more energetically favorable hydrophobic surface for the penetration and adsorption of organic species than the dt monolayer. |
