The Effect of Metal Ions on the Structure and Stability of Simulating Lipid Rafts by LB Films and AFM
金属离子对模拟脂筏结构和稳定性影响的LB膜和原子力显微镜研究

The purpose of this study is to observe the effects of metal ions, Na+, K+, Ca2+ and Mg2+ on the structure and stability of simulating lipid rafts. The metal ions are ubiquity in organisms and play key roles in them. In this study, The π-A isotherms of lipid rafts on different sub-phases were measured using the technique of Langmuir-Blodgett (LB) films, and their energetics propertics were also analyzed. The surface structures were presented by atomic force microscope (AFM). Experiments showed the effect of metal ions on the shape, size and surface structure of lipid rafts.
