The hollow structure of cyclodextrins makes them promising hosts for drugs. By attaching polymers to the cyclodextrin ring scientists can create new materials to use as drug delivery systems. One advantage of attaching the polymer is that it allows the delivery properties to be tailored by modifying the polymer as well as the cyclodextrin host.
The review by Jiawen Zhou and Helmut Ritter, Heinrich-Heine University of Düsseldorf, Germany, focuses on the recent advances made with cyclodextrins in polymer chemistry and their applications in drug delivery systems. They discuss the opportunities for using click reactions to covalently attached polymer chains to cyclodextrins, and other examples for functionalizing cyclodextrin.
