Multiphase Biomedical Materials

Following many reports that were published in the last two decades on correlations of multiphase structures of the surface of materials with their antithrombogenicity or biocompatibility a research project ''Design of Multiphase Biomedical Materials'' was carried out in Japan between 1982 and 1986. The objective of this research project was to elucidate various aspects of biomedical behaviour of multiphase systems at the interface with living bodies at the molecular, cellular and tissue levels. Multiphase materials studied cover polymers having microphase-separated structures, hydrogels, immobilized enzymes (or cells), ceramics and metallic materials. The research project was carried out by the following subgroups: -- Multiphase biomedical materials with microdomain structures -- Multiphase biomedical materials containing liquid components -- Hybrid-type multiphase biomedical materials with biological components -- Inorganic and metallic multiphase biomedical materials -- Methods for analysis and evaluation of multiphase biomedical materials This book contains the results of the research project in an edited form and aims to provoke a better understanding about various aspects of cell--material interactions in which the multiphase systems play a crucial role.

The articles collected in this publication have previously been published in eight special issues of the Journal of Biomaterials Science, Polymer Edition, in honour of Dr. Allan S. Hoffman, who is known as a pioneer, a leader and a mentor in the field of biomaterials. The papers from renowned scientists from all parts of the world, representing the

Nanofiber Composite Materials for Biomedical Applications presents new developments and recent advances in nanofiber-reinforced composite materials and their use in biomedical applications, including biomaterial developments, drug delivery, tissue engineering, and regenerative medicine. Unlike more conventional titles on composite materials, this book covers the most innovative new developments in nanofiber-based composites, including polymers, ceramics, and metals, with particular emphasis on their preparation and characterization methodology. Selected case studies illustrate new developments in clinical and preclinical use, making the information critical for the development of new medical materials and systems for use in human health care, and for the exploration of new design spaces based on these nanofibers. This book is essential reading for those working in biomedical science and engineering, materials science, nanoscience, biomedical nanotechnology, and biotechnology. Covers innovative new developments in nanofiber composites, including polymers, ceramics, and metals with particular emphasis on their preparation and characterization methodology Deals with biomedical applications, including biomaterials developments, drug delivery, tissue engineering, and regenerative medicine Presents selected case studies on nanofiber composite materials in both clinical and preclinical use

Through the integration of strategies from life science, engineering, and clinical medicine, tissue engineering and regenerative medicine hold the promise of new solutions to current health challenges. This rapidly developing field requires continual updates to the state-of-the-art knowledge in all of the aforementioned sciences. Tissue Engineering

Biomedical Materials and Diagnostics Devices provides an up-to-date overview of the fascinating and emerging field of biomedical materials and devices, fabrication, performance, and uses The biomedical materials with the most promising potential combine biocompatibility with the ability to adjust precisely the biological phenomena in a controlled manner. The world market for biomedical and diagnostic devices is expanding rapidly and the pace of academic research resulted in about 50,000 published papers in recent years. It is timely, therefore, to assemble a volume on this important subject. The chapters in the book seek to address progress in successful design strategies for biomedical materials and devices such as the use of collagen, crystalline calcium orthophosphates, amphiphilic polymers, polycaprolactone, biomimetic assembly, bio-nanocomposite matrices, bio-silica, theranostic nanobiomaterials, intelligent drug delivery systems, elastomeric nanobiomaterials, electrospun nano-matrices, metal nanoparticles, and a variety of biosensors. This large and comprehensive volume includes twenty chapters authored by some of the leading researchers in the field, and is divided into four main areas: biomedical materials; diagnostic devices; drug delivery and therapeutics; and tissue engineering and organ regeneration.

First of all, I would like to share the great pleasure of the successful five-day symposium with every participant in the 5th Iketani Conference which was held in Kagoshima from April1S (Tuesday) to 22 (Saturday), 1995. Outstanding speakers enthusiastically presented their up-to-the-minute results. Relatively little time was allotted for each presentation to ensure asdnuch time· as possible for intensive discussions on the particular topics that had just been p~esented: I was delighted to see that the lectures were of high quality, and the discu,ssionswere lively, exciting, and productive in a congenial atmosphere. We also had 92 papers in the poster ·session, in which young (and relatively young) scientists made every effort to present the novel results of their research in advanced biomaterials and drug delivery systems (DDS). I believe some of the research is most promising and will become noteworthy in the twenty-first century. It was a privilege for me to deliver a lecture at the special session of the symposium. In my introductory remarks, I pointed out five key terms in multifaceted biomaterials research: materials design, concept or methodology, devices, properties demanded, and fundamentals. I am confident that innovative progress in device manufacturing for end-use, e.g., artificial organs, vascular grafts, and DDS, can be brought about only through properly designed advanced materials that exhibit the desired functionality at the interface with any living body.

Biomedical Materials provides a comprehensive discussion of contemporary biomaterials research and development.

A pedagogical writing style and structure provides readers with an understanding of the fundamental concepts necessary to pursue research and industrial work on biomaterials, including characteristics of biomaterials, biological processes, biocompatibility, and applications of biomaterials in implants and medical instruments. Written by leading researchers in the field, this text book takes readers to the forefront of biomedical materials development, providing them with a taste of how the field is changing, while also serving as a useful reference to physicians and engineers.

Maintaining quality of life in an ageing population is one of the great challenges of the 21st Century. This book summarises how this challenge is being met by multi-disciplinary developments of specialty biomaterials, devices, artificial organs and in-vitro growth of human cells as tissue engineered constructs. Biomaterials, Artificial Organs and Tissue Engineering is intended for use as a textbook in a one semester course for upper level BS, MS and Meng students. The 25 chapters are organized in five parts: Part one provides an introduction to living and man-made materials for the non-specialist; Part two is an overview of clinical applications of various biomaterials and devices; Part three summarises the bioengineering principles, materials and designs used in artificial organs; Part four presents the concepts, cell techniques, scaffold materials and applications of tissue engineering; Part five provides an overview of the complex socio-economic factors involved in technology based healthcare, including regulatory controls, technology transfer processes and ethical issues.
