Medical Biosensors for Point of Care (POC) Applications discusses advances in this important and emerging field which has the potential to transform patient diagnosis and care. Part 1 covers the fundamentals of medical biosensors for point-of-care applications. Chapters in part 2 go on to look at materials and fabrication of medical biosensors while the next part looks at different technologies and operational techniques. The final set of chapters provide an overview of the current applications of this technology.

Traditionally medical diagnostics have been dependent on sophisticated technologies which only trained professionals were able to operate. Recent research has focused on creating point-of-care diagnostic tools. These biosensors are miniaturised, portable, and are designed to be used at the point-of-care by untrained individuals, providing real-time and remote health monitoring.

Monitoring and Evaluation of Biomaterials and Their Performance In Vivo provides essential information for scientists and researchers who need to assess and evaluate performance, monitor biological responses, gauge efficacy, and observe changes over time. Crucially, it also enables the optimization of design for future biomaterials and implants.

This book presents readers with comprehensive coverage of the topic of in vivo monitoring of medical implants and biomaterials.

Nanobiomaterials: Nanostructured materials for biomedical applications covers an extensive range of topics related to the processing, characterization, modeling, and biomedical applications of nanostructured ceramics, polymers, metals, composites, self-assembled materials, and macromolecules. Novel approaches for bottom-up and top-down processing of nanostructured biomaterials are highlighted. In addition, innovative techniques for characterizing the in vitro behavior and in vivo behavior of nanostructured biomaterials are considered. Applications of nanostructured biomaterials in dentistry, drug delivery, medical diagnostics, surgery and tissue engineering are examined.

Rapid Prototyping of Biomaterials: Techniques in Additive Manufacturing, Second Edition, provides a comprehensive review of emerging rapid prototyping technologies, such as bioprinting, for biomedical applications. Rapid prototyping, also known as additive manufacturing, solid freeform fabrication, or 3D printing, can be used to create complex structures and devices for medical applications from solid, powder or liquid precursors. Sections explore a variety of materials, look at applications, and consider the use of rapid prototyping technologies for constructing organs. With its distinguished editor and international team of renowned contributors, this book is a useful, technical resource for scientists and researchers in academia, biomaterials and tissue regeneration.

Biologically functional ceramic materials have been known about for several decades, like phosphate cements and gypsum, and they are within the zeroth generation. Modern and artificially synthesized bioceramics include amorphous materials in the Bioglass� family that were developed in the early 1970's and derivative glass ceramics such as Bioverit� and Cerabone A-W� that came in 1980's. They are from the 2nd generation of materials, and mostly applicable to bone replacement or bone defect fillers. Since the late 1990's, newer technologies have been introduced to the biologically functional material fields; they are the syntheses of organic-inorganic hybrids of micro- and macroscopic scales as well as nano-scales, organic fragment-covered ceramic particles of varied sizes, with light-controlling abilities to modify the frequency of light, in addition synthesis of high strength and high-tribological durability that had not been available before. With the advent of additive manufacturing technology employing lasers, electron beams, and printers, clinical materials of complicated porous structures are now easily prepared. These materials are of the 3rd generation.

This book will cover almost all kinds of such 3rd generation ceramic and ceramic-related biomaterials. This book conveys the current state-of-the-art on the science and technology of bioceramics, from nano-size dots or particles to macro-scale architectures, of a wide range of constitutions including quantum dots with peptide fragments, meso-scale therapeutic particles designed to involve drugs or genes, mesoporous organic-inorganic hybrids, nano-structured oxide layers on metals and alloys.

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 issue contains the proceedings of the "Porous Ceramics: Novel Developments and Applications" and "Next Generation Bioceramics" symposia, which were held on January 24-29, 2010 at the Hilton Daytona Beach Resort and the Ocean Center in Daytona Beach, Florida, USA.

The interaction between ceramic materials and living organisms is a leading area of ceramics research. Novel bioceramic materials are being developed that will provide improvements in diagnosis and treatment of medical and dental conditions. In addition, bioinspired ceramics and biomimetic ceramics have generated considerable interest in the scientific community. The "Next Generation Bioceramics" symposium addressed several leading areas related to the development and use of novel bioceramics, including advanced processing of bioceramics; biomineralization and tissue-material interactions; bioinspired and biomimetic ceramics; ceramics for drug delivery; ceramic biosensors; in vitro and in vivo characterization of bioceramics; mechanical properties of bioceramics; and nanostructured bioceramics.

The "Porous Ceramics" symposium aimed to bring together engineers and scientists in the area of ceramic materials containing high volume fractions of porosity, in which the porosity ranged from nano- to millimeters. These materials have attracted significant academic and industrial attention for use in environmental applications, an area where ceramics, particularly porous ones, play a key role because of their suitable properties. Therefore, a significant number of contributions, of which some are present in this volume, was devoted to the fabrication and characterization of porous ceramics for gas purification (e.g., H2 separation and CO2 separation) as well as to particulate filtration (e.g., diesel engine soot).

A leading area of ceramics research involves the development of porous ceramics for medical, dental, and biotechnology applications. For example, porous ceramics are under development for use as bone substitutes because a porous structure may enhance tissue ingrowth. Therefore, tailoring of porosity to give specific characteristics, in terms of the amount of interconnecting cells and of the cell and cell window size is required. A joint session involving participants from bioceramics and porous ceramics symposia was therefore held in order to stimulate discussion and productive interactions between the two scientific communities.
