Proceedings of a consultants meeting on radiation processing of polysaccharides, held at the Takasaki Radiation Chemistry Research Establishment (TRCRE), Japan, 24-27 November 2003

Radiation-Processed Polysaccharides: Emerging Roles in Agriculture is the first book to focus exclusively on this emerging and important option for reducing the overuse and negative impact of agrochemicals in agriculture. Among practices being developed for effective and eco-friendly plant growth regulators in crop production, using radiation-processed polysaccharides (RPPs) is a promising technique. Comprised of chapters from diverse areas of plant science, including agriculture, agronomy, biotechnology, nanotechnology, molecular biology, and radiation agriculture, this book provides insights into the practical application of RPPs and inspires further research toward sustainable and efficient agricultural production. Polysaccharides (sodium alginate, carrageenan, chitosan and others) in their depolymerized state are increasingly important to agriculture based on their unique biological properties, biocompatibility, biodegradability and non-toxicity. Understanding the impact of RPPs on the plant phenotype, translocation of nutrients from source to sink, signal processing, and crosstalk helps improve the applicability of RPPs and sustainable agricultural yield. - Presents the latest application of RPPs for improved plant production - Includes insights for abiotic stress, biotechnology, nanotechnology and molecular application - Explores the efficiency of natural polysaccharides as plant growth promoters

This publication provides the background and compiles the most recent research findings as well as detailing development activities relating to the development of radiation processed products made of natural polymers. Successes clearly indicate that the radiation processing of natural polymers has emerged as an exciting area where the unique characteristics of these polymeric materials can be exploited for a variety of practical applications in agriculture, healthcare, industry and the environment.

Radiation processing is a very convenient tool for imparting desirable effects in polymeric materials and it has been an area of enormous interest in the last few decades. The success of radiation technology for processing of synthetic polymers can be attributed to two reasons namely, their ease of processing in various shapes and sizes, and secondly, most of these polymers undergo crosslinking reaction upon exposure to radiation. In recent years, natural polymers are being looked at with renewed interest because of their unique characteristics, such as inherent biocompatibility, biodegradabil.

​This book provides an introduction of how radiation is processed in polymeric materials, how materials properties are affected and how the resulting materials are analyzed. It covers synthesis, characterization, or modification of important materials, e.g. polycarbonates, polyamides and polysaccharides, using radiation. For example, a complete chapter is dedicated to the characterization of biodegradable polymers irradiated with low and heavy ions. This book will be beneficial to all polymer scientists in the development of new macromolecules and to all engineers using these materials in applications. It summarizes the fundamental knowledge and latest innovations in research fields from medicine to space.

This book provides the whole spectrum of polysaccharides from basic concepts to commercial market applications. Chapters cover various types of sources, classification, properties, characterization, processing, rheology and fabrication of polysaccharide-based materials and their composites and gels. The applications of polysaccharides include in cosmetics, food science, drug delivery, biomedicine, biofuel production, marine, packaging, chromatography and environmental remediation. It also reviews the fabrication of inorganic and carbon nanomaterials from polysaccharides. The book incorporates industrial applications and will fill the gap between the exploration works in the laboratory and viable applications in related ventures.

Seaweed Polysaccharides: Isolation, Biological, and Biomedical Applications examines the isolation and characterization of algal biopolymers, including a range of new biological and biomedical applications. In recent years, significant developments have been made in algae-based polymers (commonly called polysaccharides), and in biomedical applications such as drug delivery, wound dressings, and tissue engineering. Demand for algae-based polymers is increasing and represent a potential—very inexpensive—resource for these applications. The structure and chemical modification of algal polymers are covered, as well as the biological properties of these materials – including antithrombic, anti-inflammatory, anticoagulant, and antiviral aspects. Toxicity of algal biopolymers is also covered. Finally, the book introduces and explains real world applications of algal-based biopolymers in biomedical applications, including tissue engineering, drug delivery, and biosensors. This is the first book to cover the extraction techniques, biomedical applications, and the economic perspective of seaweed polysaccharides. It is an essential text for researchers and industry professionals looking to work with this renewable resource. - Provides comprehensive coverage of the research currently taking place in biomedical applications of algae biopolymers - Includes practical guidance on the isolation, extraction, and characterization of polysaccharides from sustainable marine sources - Covers the extraction techniques, biomedical applications, and economic outlook of seaweed polysaccharides

Renowned experts give all essential aspects of the techniques and applications of graft copolymers based on polysaccharides. Polysaccharides are the most abundant natural organic materials and polysaccharide based graft copolymers are of great importance and widely used in various fields. Natural polysaccharides have recently received more attention due to their advantages over synthetic polymers by being non-toxic, biodegradable and available at low cost. Modification of polysaccharides through graft copolymerization improves the properties of polysaccharides. Grafting is known to improve the characteristic properties of the backbones. Such properties include water repellency, thermal stability, flame resistance, dye-ability and resistance towards acid-base attack and abrasion. Polysaccharides and their graft copolymers find extensive applications in diversified fields. Applications of modified polysaccharides include drug delivery devices, controlled release of fungicides, selective water absorption from oil-water emulsions, purification of water etc.
