| 中文摘要 | atomic force microscopy (afm) and lateral force microscopy (lfm) were used simultaneously to analyze a model membrane bilayer structure consisting of a phospholipid outer monolayer deposited onto organosilane-derivatized mica surfaces, which were constructed by using painting and self-assembly methods. the phospholipid used as outer monolayer was dimyristoylphosphatidylcholine (dmpc). the hydrocarbon-covered substrate that formed the inner half bilayer was composed of a self-assembly monolayer (sam) of octadecyltrichloroorganosilane (ots) on mica. sams of dmpc were formed by exposing hydrophobic mica to a solution of dmpc in decane/isobutanol and subsequently immersing into pure water. afm images of samples immersed in solution for varying exposure times showed that before forming a complete monolayer the molecules aggregated into dense islands (2.2-2.6 nm high) on the surface. the islands had a compact and rounded morphology. lfm, coupled with topographic data obtained with the atomic force mode, had made possible the distinction between dmpc and ots. the rate constant of dmpc growth was calculated. this is the first systematic study of the sam formation of dmpc by afm and lfm imaging. it reveals more direct information about the film morphology than previous studies with conventional surface analytical techniques such as infrared spectroscopy, x-ray, or fluorescence microscopy. |
