Casettari, Luca and Vllasaliu, Driton and Castagnino, Enzo and Stolnik, Snjezana and Howdle, Steven and Illum, Lisbeth (2012) PEGylated chitosan derivatives: synthesis, characterizations and pharmaceutical applications. Progress in Polymer Science, 37 (5). pp. 659-685. ISSN 0079-6700Full text not available from this repository.
This review sets out to describe and discuss the synthetic approaches and the fields of application of PEGylated chitosan copolymers especially for medical use. The PEGylation of chitosan and chitosan derivatives is able to add new physicochemical properties to the cationic polysaccharide polymers, thereby overcoming some limitations, especially regarding their solubility and their use in drug and gene delivery (DNA and siRNA). All methods of derivatization have been considered and described together with the different methods of characterization of the copolymers. The capacities of PEGylated chitosan to reduce chitosan toxicity, to enhance membrane permeation and to form thermosensitive hydrogels have also been discussed.
