This book covers important topics of Biopolymers nanocomposites in simple language with clear presentation. Traces of their use as biomedical and pharmaceutical application, gelatine, polysacharides based nanocomposites for applications in antibacterial/microbial/biomedical engineering, drug delivery system and tissue engineering is covered. Further, it presents the opportunities and applications in the field of biocomposites highlighting recent advances in areas commencing chemical synthesis and biosynthesis for end-user applications. This book will serve as a comprehensive literature guide for beginner researchers to grab the attention of biomedical researchers in both academia and industries to help streamline the efforts and understand the need to develop new biocomposites that could solve some of the most serious biomedical problems. The book is aimed to be a reference material for the academic and research community involved in biomedical research.
