Cyclodextrins are a family of cyclic oligosaccharides that are composed of several glucose units linked together. They have a unique cone-shaped structure that allows them to form inclusion complexes with a variety of guest molecules, such as drugs, fragrances, and dyes. Cyclodextrins are widely used in pharmaceuticals, food, cosmetics, and other industries as solubilizing agents, stabilizers, and drug delivery systems. Research in the area of cyclodextrins focuses on their synthesis, characterization, applications, and potential for improving the solubility, stability, and bioavailability of various compounds.
