通过蒸发诱导自组装，在固体表面沉积了高度取向的片状纳米颗粒-磷脂纳米复合材料。透射电子显微镜、X射线反射率、掠入射X射线衍射和光致发光光谱测试表明，纳米粒子均匀分散在脂质双层之间的界面区。通过调节纳米颗粒和磷脂的相对浓度和/或在脂质双层中加入带电磷脂，可以很容易地控制层状纳米复合材料的周期和颗粒间的分离。
Highly oriented lamellar nanoparticle-phospholipid nanocomposites are deposited on solid surfaces via evaporation-induced self-assembly. The TEM, X-ray reflectivity, grazing incident X-ray diffraction, and photoluminescence spectrum measurements show that the nanoparticles are homogeneously dispersed in the interfacial regions between the lipid bilayers. The period of the lamellar nanocomposites and the interparticle separation can be readily controlled by adjusting the relative concentration of the nanoparticles and the phospholipids and/or by adding charged phospholipids into the lipid bilayers.
