Book Description
ASTM Committee on F4 Medical and Surgical Materials and Devices, Division IV, Tissue Engineered Medical Products (TEMPs), Biomaterials and Biomolecules for TEMPs Subcommittee (F4.42) has been developing standards for characterizing natural materials used in TEMPs. Natural materials include alginate, chitosan, collagen and hyaluronate. These materials support cell growth and differentiation on TEMPs substrates and scaffolds. Natural materials have been used in a variety of applications, including encapsulation, cell seeding, development of "memory" biomaterials, as well as degradable scaffolds, growth factor/nucleic acid delivery vehicles, and as a carrier to improve product handling characteristics. These materials have typically been very poorly characterized as to their chemical, physical and biological properties. This has resulted in variability in the products produced from these starting materials. The development of Standard Guides and Test Methods for characterizing natural materials is anticipated to reduce the variability of these starting materials and to aid in the assessment of the safety of the subsequent TEMPs.

Book Description
On June 13-14, 2001, the National Institute of Standards and Technology (NIST) convened a workshop of high level representatives from industry, federal agencies, and standards organizations to identify standards-related needs of the biomedical materials and devices industry. There were individual breakout sessions on standards for: Biomaterials, Therapeutic and Drug Delivery Devices, Auditory Diagnostic and Prosthetic Devices, Manufacturing of Prostheses, and Tissue Engineered Medical Products (TEMPs). Cross-cutting issues of Harmonization of Standards, Data, and Sterilization were also addressed. The session on Standards for TEMPs placed its most significant needs on the development of test methods and materials characterization. Action items for NIST to consider were separated into those relative to the Food and Drug Administration (FDA) approval process and those relative to industry needs not directly related to the FDA approval process. This paper summarizes the needs identified for TEMPs and the status of NIST-related activities.

Book Description
As a spectroscopic method, nuclear magnetic resonance (NMR) has seen spectacular growth, both as a technique and in its applications. Today's applications of NMR span a wide range of scientific disciplines, from physics to biology to medicine. Each volume of Nuclear Magnetic Resonance comprises a combination of annual and biennial reports which together provide comprehensive coverage of the literature on this topic. This Specialist Periodical Report reflects the growing volume of published work involving NMR techniques and applications, in particular NMR of natural macromolecules, which is covered in two reports: NMR of Proteins and Nucleic Acids; and NMR of Carbohydrates, Lipids and Membranes. For those wanting to become rapidly acquainted with specific areas of NMR, Nuclear Magnetic Resonance provides unrivalled scope of coverage. Seasoned practitioners of NMR will find this an invaluable source of current methods and applications. Specialist Periodical Reports provide systematic and detailed review coverage in major areas of chemical research. Compiled by teams of leading experts in their specialist fields, this series is designed to help the chemistry community keep current with the latest developments in their field. Each volume in the series is published either annually or biennially and is a superb reference point for researchers. www.rsc.org/spr

Book Description
Revised, expanded, and updated, Orthopaedic Biomaterials in Research and Practice, Second Edition introduces materials science and applies it to medical research and treatment. This book incorporates math and engineering, which makes it accessible to trainees and others working in the industry who are lacking primary mathematical and engineering training. What’s New in the Second Edition: In the second edition, the new material includes regeneration, hybrid and replant materials, tissue engineering, electrical stimulation for tissue growth and repair, modeling of material behavior in service, and long-term function of materials in patients. It explores tools for non-destructive and destructive analysis of explanted devices, and provides updates on all material classes including shape memory and degradable alloys, fracture-resistant ceramics, and bioabsorbable polymers. It provides a compendium for implant host response including in-depth discussion of metallosis and hypersensitive response. It also adds new case studies, worked problems, and a complete self-evaluation test with annotated answers. Includes focused, practical study questions after each chapter Presents extensive, detailed figures accompanying example problems and concepts Provides a one-stop reference for understanding all biomaterials that are used in contemporary orthopaedic surgery and beyond Introduces key concepts of relevance in each chapter Orthopaedic Biomaterials in Research and Practice, Second Edition serves as a textbook for orthopaedic residents. It can also serve as a review for the Orthopaedists In-Training Examination (OITE), the Orthopaedic Self-Assessment Examination, or the Orthopaedic Board Examination.

Book Description
More often than not users of biopolymers obtain their starting materials from a chemical supply company. Documentation is often lacking and the user is not aware of the fact that a biopolymer's functionality in an application is inherently linked to its characteristics. As a manufacturer of ultrapure biopolymers we have often heard the comment that "your biopolymer didn't work!" More often than not, however, the functional properties of the polymer were not appropriate for the intended use. Variability in naturally occurring biopolymers can lead to failed formulations. Alginate and chitosan are biopolymers that may be used in TEMPs. Derived from natural sources, these materials are particularly complex, and thus exhibit significant variability. Consequently, in order to understand the full range of their properties there is a need for accurate characterization of these materials. The development of standards for such TEMP starting materials is necessary to ensure product uniformity, enable more complete and precise characterization and to inform both users and manufacturers of the relationships among composition, functional properties and utility. This can only lead to more successful TEMP formulations.

Book Description
This brief introductory chapter provides a broad overview of materials, biomaterials and the need to understand different techniques to characterize biomaterials. From this chapter, the reader can gain a perspective on how the rest of the topics in different chapters are divided to fully comprehend this inherently multidisciplinary field. Application of appropriate characterization tools can not only save time to fully evaluate different biomaterials, it can also make commercial biomedical devices safer. In the long run, safer biomedical devices can only reduce the pain and suffering of mankind, a dream that resonates with every biomedical researcher.
