The comprehensive resource for understanding the structure, properties, and applications of cyclodextrins Cyclodextrins: Properties and Industrial Applications is a comprehensive resource that includes information on cyclodextrins (CDs) structure, their properties, formation of inclusion complex with various compounds as well as their applications. The authors Sahar Amiri and Sanam Amiri, noted experts in the field of cyclodextrins, cover both the basic and applied science in chemistry, biology, and physics of CDs and offers scientists and engineers an understand of cyclodextrins. Cyclodextrins are a family of cyclic oligosaccharides consisting of (α-1,4)-linked α-D-glucopyranose units. The formation of inclusion complex between CDs as host and guest molecules is based on non-covalent interaction such as hydrogen bonding or van der waals interactions and lead to the formation of supramolecular structures. These supramolecular structures can be used as macroinitiator for initiating various type of reactions. CDs are widely used in many industrial products such as pharmacy, food and flavours, chemistry, chromatography, catalysis, biotechnology, agriculture, cosmetics, hygiene, medicine, textiles, drug delivery, packing, separation processes, environment protection, fermentation, and catalysis. This important resource: Offers a basic understanding of cyclodextrins for researchers and engineers Includes information of the basic structure of cyclodextrins and their properties Reviews how cyclodextrins can be applied in a variety of fields including medicine, chemistry, textiles, packing, and many others Shows how encapsulate corrosion inhibitors became active in corrosive electrolytes to ensure delivery of the inhibitors to corrosion sites and long-term corrosion protection Cyclodextrins offers research scientists and engineers a wealth of information about CDs with particular focus on how cyclodextrins are applied in various ways including in drug delivery, the food industry, and many other areas.

Through modification, the natural cyclodextrins are effective templates for the generation of a wide range of molecular hosts. This makes it possible to tailor a cyclodextrin host to a particular guest, to meet specific requirements in the host-guest complex, and opens the way to diverse new areas of supramolecular chemistry. Metallocyclodextrins, rotaxanes and catenanes, as well as surface monolayers of modified cyclodextrins, are readily obtained. The native cyclodextrins serve as scaffolds on which functional groups and other substituents can be assembled, with controlled geometry. This results in substantially improved molecular recognition and procedures for chemical separation, including enantiomer discrimination, through guest binding. Access to the gamut of functional groups greatly expands the utility of cyclodextrins in chemical synthesis and provides catalysts which mimic the entire range of enzymic activity. Modifications to the cyclodextrins also lead to a wide range of photochemistry of cyclodextrin complexes, through which the enhancement of guest reactivity occurs; in addition, light harvesting molecular devices and photochemical frequency switches may be constructed. In solution, modified cyclodextrins have been used to construct molecular reactors, as well as molecular, temperature and pH sensors. At surfaces, they form semipermeable membranes and sensor electrodes. Such exciting fields of chemistry, made possible only through modifications to the natural cyclodextrins, are the subject of this book.
