合成了三种类型的天然环糊精封端的金纳米颗粒，允许精确控制其尺寸范围从9到20 nm。这些纳米颗粒在长期储存期间表现出显着的胶体稳定性，以及对盐、酸性和碱性条件的优异耐受性。重要的是，通过使用肉桂基官能化的二氧化硅纳米球和用三种类型的环糊精封端的金纳米颗粒来进行纳米颗粒的组装，突出了基于不同纳米颗粒之间纳米表面上的主客体分子识别的核-卫星超结构的选择性形成。
Gold nanoparticles capping with three types of natural cyclodextrins are synthesized, allowing for precise control over their sizes ranging from 9 to 20 nm. These nanoparticles exhibit remarkable colloidal stability during long‐term storage, as well as excellent tolerance to saline, acidic, and alkaline conditions. Importantly, the assembly of nanoparticles is performed by using the silica nanospheres functionalized with cinnamyl group and the gold nanoparticle capping with three types of cyclodextrin, highlighting the selective formation of core‐satellite superstructure based on the host–guest molecular recognition on nano‐surface between different nanoparticles.
