Abstract
AbstractGold 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.
