Cyclodextrins (CDs) are cyclic oligosaccharides composed of D-glucose units that are joined by α-1
4-glucosidic linkages
which contain a hydrophilic outer surface and a hydrophobic cavity. Cyclodextrin and its derivatives can form inclusion complexes with suitable hydrophobic guest molecules through host-guest interaction. This review describes the structure and property of the cyclodextrin and the design principles
mechanisms
stimuli responses
and applications of the supramolecular assemblies such as nanoparticles
