Book Description
Biodegradable, polymer-based systems are playing an increasingly pivotal role in tissue engineering replacement and regeneration. This type of biology-driven materials science is slated to be one of the key research areas of the 21st century. The following aspects are crucial: the development of adequate human cell culture to produce the tissues in adequate polymer scaffold materials; the development of culture technology with which human tissues can be grown ex-vivo in 3D polymer matrices; the development of material technology for producing the degradable, 3D matrices, having mechanical properties similar to natural tissue. In addressing these and similar problems, the book contains chapters on biodegradable polymers, polymeric biomaterials, surface modification for controlling cell-material interactions, scaffold design and processing, biomimetic coatings, biocompatibility evaluation, tissue engineering constructs, cell isolation, characterisation and culture, and controlled release of bioactive agents.

Book Description
Bioresorbable materials are extensively used for a wide range of biomedical applications from drug delivery to fracture fixation, and may remain in the body for weeks, months or even years. Accurately predicting and evaluating the degradation rate of these materials is critical to their performance and the controlled release of bioactive agents. Degradation rate of bioresorbable materials provides a comprehensive review of the most important techniques in safely predicting and evaluating the degradation rate of polymer, ceramic and composite based biomaterials.Part one provides an introductory review of bioresorbable materials and the biological environment of the body. Chapters in Part two address degradation mechanisms of commonly used materials such as polymers and ceramics. This is followed by chapters on bioresorption test methods and modelling techniques in Part three. Part four discusses factors influencing bioresorbability such as sterilisation, porosity and host response. The final section reviews current clinical applications of bioresorbable materials.With its distinguished editor and multidisciplinary team of international contributors, Degradation rate of bioresorbable materials: prediction and evaluation provides a unique and valuable reference for biomaterials scientists, engineers and students as well as the medical community. - Comprehensively reviews the most pertinent techniques in safely predicting and evaluating the degradation rate of bioresorbable materials - Addresses degradation mechanisms of commonly used materials - Discusses factors influencing bioresorbability such as sterilisation and host response

Book Description
This book summarizes the properties and applications of conventional and commercially available fiber-forming, bioresorbable polymers, as well as those currently under study, for use as biotextiles. Factors affecting the performance of these biomaterials are presented, and precautionary measures to reduce premature, hydrolytic degradation during manufacturing and processing are discussed. Because of the structural requirements of medical devices and the technological advancements in synthetic fibers and textile technology, the new field of "Biotextiles" has evolved to exploit the potential of various woven, knitted, braided and non-woven textile structures for biomedical applications. Textile substrates provide certain unique mechanical properties to the medical device and because of an inherently high level of porosity, they can encourage cell growth and promote migration and proliferation. Bioresorbable devices that assist in the repair and regeneration of damaged tissues have in recent years replaced many of the permanent prosthetic devices. Thus, the topic of “Bioresorbable Biomaterials” generates much interest and research activity in the field of biomaterials science today. For this reason, the use of bioresorbable polymers as fibers is currently dominating the field of resorbable biomaterials for applications from sutures to tissue engineering scaffolds.
