Biomedical Materials And Diagnostic Devices

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.

Biomedical Materials provides a comprehensive discussion of contemporary biomaterials research and development. Highlighting important topics associated with Engineering, Medicine and Surgery, this volume reaches a wide scope of professionals, researchers and graduate students involved with biomaterials. 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.

This book presents an introduction to biomaterials with the focus on the current development and future direction of biomaterials and medical devices research and development in Indonesia. It is the first biomaterials book written by selected academic and clinical experts experts on biomaterials and medical devices from various institutions and industries in Indonesia. It serves as a reference source for researchers starting new projects, for companies developing and marketing products and for governments setting new policies. Chapter one covers the fundamentals of biomaterials, types of biomaterials, their structures and properties and the relationship between them. Chapter two discusses unconventional processing of biomaterials including nano-hybrid organic-inorganic biomaterials. Chapter three addresses biocompatibility issues including in vitro cytotoxicity, genotoxicity, in vitro cell models, biocompatibility data and its related failure. Chapter four describes degradable biomaterial for medical implants, which include biodegradable polymers, biodegradable metals, degradation assessment techniques and future directions. Chapter five focuses on animal models for biomaterial research, ethics, care and use, implantation study and monitoring and studies on medical implants in animals in Indonesia. Chapter six covers biomimetic bioceramics, natural-based biocomposites and the latest research on natural-based biomaterials in Indonesia. Chapter seven describes recent advances in natural biomaterial from human and animal tissue, its processing and applications. Chapter eight discusses orthopedic applications of biomaterials focusing on most common problems in Indonesia, and surgical intervention and implants. Chapter nine describes biomaterials in dentistry and their development in Indonesia.

are then selected and must meet the general 'biocompatibility' require ments. Prototypes are built and tested to include biocompatibility evalua tions based on ASTM standard procedures. The device is validated for sterility and freedom from pyrogens before it can be tested on animals or humans. Medical devices are classified as class I, II or III depending on their invasiveness. Class I devices can be marketed by submitting notification to the FDA. Class II and III devices require either that they show equivalence to a device marketed prior to 1976 or that they receive pre-marketing approval. The time from device conception to FDA approval can range from months (class I device) to in excess of ten years (class III device). Therefore, much planning is necessary to pick the best regulatory approach. 2. Wound Dressings and Skin Replacement 2.1 Introduction Wounds to the skin are encountered every day. Minor skin wounds cause some pain, but these wounds will heal by themselves in time. Even though many minor wounds heal effectively without scarring in the absence of treatment, they heal more rapidly if they are kept clean and moist. Devices such as Band-Aids are used to assist in wound healing. For deeper wounds, a variety of wound dressings have been developed including cell cultured artificial skin. These materials are intended to promote healing of skin damaged or removed as a result of skin grafting, ulceration, burns, cancer excision or mechanical trauma.

This book highlights the responsibility of medical device designers and engineers to eliminate sites of failure and to test devices to demonstrate their ultimate safety and efficacy. It also evaluates biomaterials and their properties as related to the design and reliability of medical devices. The principles that are described are readily applicable to the biomaterial scaffolds used for generating tissue-engineered constructs.
