摘要：
The CD's stuck: Poly(ethylene glycol) chains anchored onto gold nanoparticles (AuNPs) are threaded by multiple α-cyclodextrin (α-CD) rings to form a supramolecular outer layer composed of pseudopolyrotaxane columns perpendicular to the nanoparticle surface. Capping the polymer ends confines α-CD on the nanoparticle surface, cross-linking the α-CD rings and then removing the AuNP cores produces supramolecular nanocapsules. © 2009 Wiley-VCH Verlag GmbH & Co.
