A Review on Grafting Modification of Polysaccharides by Microwave Irradiation- Distinctive Practice for Application in Drug Delivery
نویسندگان
چکیده
Most of the natural polysaccharides have been used as food and pharmaceutical excipients due to their biodegradability, biocompatibility, low cost and easy availability. Diverse approaches such as etherification, crosslinking and graft co-polymerization can be used for the chemical modification of natural polymers. Grafting process is a suitable method to add new properties to a natural polymer with minimum loss of the initial properties of the substrate. Water is used as a solvent in most of the polysaccharide grafting reactions, as many polysaccharides are soluble in water. This review highlights modern applications of microwave heating in the grafting modifications of polysaccharides and discusses the fundamental mechanisms of grafting.
