Abstract
Alginates are natural biopolymers, which have extensively been employed for the use in drug delivery applications owing to bioadhesivity, biodegradability, non-toxicity and ease of availability. It possesses numerous distinct properties for developing different biomedical composites with other biopolymers for a broad area of biomedical applications like drug delivery, tissue engineering, wound healing, etc. Alginate-based biocomposite systems are the exclusive carriers for the applications in controlled drug delivery owing to their potency to encapsulate and delivery of numerous therapeutic agents. Besides the simpler processing techniques, mechanical strength, good bioavailability, controlled release rates, stability, targeted delivery of various agents and large-scale manufacturing with cost-effectiveness are the advantages of these alginate-based biocomposites. The current chapter presents a comprehensive review on various alginate-based biocomposites (both alginate-other biopolymeric and alginate-bioinorganic biocomposites) and their applications in drug delivery. In addition, a brief introduction about composites and biocomposites along with sources, chemistry and various important properties of alginates are discussed.
