Alginate is a hydrophilic, biocompatible, biodegradable, and relatively economical polymer generally found in marine brown algae. The modification in the alginate molecule after polymerization has shown strong potential in biomedical, pharmaceutical and biotechnology applications such as wound dressing, drug delivery, dental treatment, in cell culture and tissue engineering. Besides this, alginates have industrial applications too in the paper and food industries as plasticizers and additives. The few books that have been published on alginates focus more on their biology. This current book focuses on the exploration of alginates and their modification, characterization, derivatives, composites, hydrogels as well as the new and emerging applications.

This new volume explores the latest research on the use of alginate as a biopolymer in various biomedical applications and therapeutics. The uses of alginates and modified alginates discussed in this book include tissue regeneration, encapsulation and delivery of drugs, nucleic acid materials, proteins and peptides, genes, herbal therapeutic agents, nutraceuticals, and more. This book also describes the synthesis and characterizations of various alginate and modified alginate systems, such as hydrogels, gels, composites, nanoparticles, scaffolds, etc., used for the biomedical applications and therapeutics. Alginate, a biopolymer of natural origin, is of immense interest for its variety of applications in pharmaceuticals (as medical diagnostic aids) and in materials science. It is the one of the most abundant natural biopolymers and is considered an excellent excipient because of its non-toxic, stable, and biodegradable properties. Several research innovations have been made on applications of alginate in drug delivery and biomedicines. There needs to be a thorough understanding of the synthesis, purification, and characterization of alginates and its derivatives for their utility in healthcare fields, and this volume offers an abundance of information toward that end.

Alginates are polysaccharides found in both the intercellular matrix of brown algae and extracellularly covering some species of bacteria. Alginate varies in composition of the algae from 20% to 60% dry matter, but on average brown algae species has 40% alginate. Alginate from brown algae occurs as gels containing sodium, calcium, strontium, magnesium, and barium ions. They are widely used by the food industry, giving foods texture properties such as thickening, adhesion, emulsification, gelling, or fullness. This book covers the latest uses of this phycocolloid in the pharmaceutical, medical, and technological fields, namely bioink for 3D bioprinting in tissue engineering and regenerative medicine, and the application of artificial intelligence in modern healthcare systems.

This book presents a comprehensive review of the latest advances in developing alginate-based biomaterials and derivatives as well as their biomedical and pharmaceutical applications. It covers the physiochemical properties of alginates, production and formulation methods, derivatizations and characterization methods, the fundamental work on optimizing alginate polymers for defined biomedical purposes as well as the scope and effectiveness of their applications in medicine and therapeutic approaches. The book brings together new concepts and advances in harnessing alginate-based biomaterials in combination with applied technological advances to tailor their applications to medical needs. The contributions by leading academics, clinicians and researchers not only cover the fundamentals, but also open new avenues for meeting future challenges in research and clinical applications.
