Elsevier Natural-Based Polymers for Biomedical Applications (Woodhead Publishing Series in Biomaterials)

Natural origin biopolymers are attractive for use in biomedical applications, partly due to their biocompatibility and degradation characteristics. Natural-based polymers for biomedical applications comprehensively reviews this important subject in six in-depth sections. Part one discusses the sources, properties, modification and processing of natural-based polymers, whilst in the second section surface aspects are reviewed. Parts three and four concern natural-origin materials for tissue engineering and regenerative medicine, discussing scaffolds, hydrogels and injectable systems. The sustained release of molecules is reviewed in the fifth part of the book, followed by the biocompatibility of natural-based polymers in the final section. Key Features: examines the sources, processing and properties of natural based polymers for biomedical applications; explains how the surfaces of polymer based biomaterials can be modified to improve their functionality; discusses the use of natural based polymers for hydrogels in tissue engineering, and inparticular natural gelling polymers for encapsulation and regenerative medicine; summarises the use of natural based polymers as delivery systems for drugs, hormones, enzymes and growth factors.
