Current Opinion in Supramolecular Assemblies via Cyclodextrin‐Based Host–Guest Interactions: Concepts and Applications

Cyclodextrin is a typical macrocyclic molecule that can recognize and bind numerous guest molecules with specific structure and functional groups. The cyclodextrin-based supramolecular nanostructures, characterized by well-defined, ordered, compact, and regular molecular arrangements, are widely utilized in drug delivery, sensing, and light-harvesting systems. Their unique physicochemical properties have further expanded the scope of research in both biophysics and chemistry. In this review, we provide an overview of the concepts and applications of cyclodextrin-based supramolecular nanostructures, with a focus on their relevance to biochemistry and chemistry.
