The second edition of Chitin underscores the important factors for standardizing chitin processing and characterization. It captures the essential interplay between chitin's assets and limitations as a biomaterial, placing the past promises of chitin in perspective, addressing its present realities and offering insight into what is required to realize chitin's destiny (including its derivative, chitosan) as a biomaterial of the twenty-first century. This book is an ideal guide for both industrialists and researchers with a vested interest in commercializing chitin.An update on the research since 2001 as it pertains to the biomaterials and biomedical applications of chitin and chitosanAn expanded discussion on positioning chitin and chitosan for biomedical applicationsPresents regulatory aspects of chitin and chitosan
