Despite advances in alternative materials, metals are still the biomaterial of choice for a number of clinical applications such as dental, orthopedic and cardiac implants. However, there are a number of intrinsic problems associated with implanting metal in the biological environment, such as wear, corrosion, biocompatibility and toxicity, which must be addressed. Modern technology has enabled scientists to modify metal surfaces or apply special coatings to metals to improve their performance safety. Surface Coating and Modification of Metallic Biomaterials will discuss the most important modification techniques and coatings for metals, first covering the fundamentals of metals as a biomaterial and then exploring surface modification techniques and coatings. An expansive overview of surface modification techniques for biomedical use In-depth exploration of issues arising from metal biomaterial use Includes examples of applications in a clinical setting

The biomaterials technology industry is already well established in the western world and is growing rapidly within Asian Pacific nations. It is often described as the ‘next electronics industry’, whilst the laser is described as a ‘solution looking for a problem’. This book describes the use of the laser to solve a troublesome and costly problem in a rapidly growing global industry. The authors have spent many years conducting research using laser materials processing and wettability characteristics and have perfected a technique to improve the bio-compatibility of various bone-implant materials using laser irradiation. They have made pioneering discoveries on the subject and established some generic theories and principals that will have a wide range of applications in the biomaterials field. Introduces inter-disciplinary research work covering laser materials processing and surface modification of biomaterials for enhanced compatibility. Includes highly scientific and novel research material. Serves both as a practitioner guide and a reference book. Covers an exciting and rapidly developing area of technology that is of keen interest to engineers and clinicians alike. Laser Surface Treatment of Bio-Implant Materials is rare in providing a reference source that describes specifically a mechanical engineering solution to a biotechnology problem. It serves as both a practitioner guide and a medium to high-level reference text book, and as such is a reference source for the engineer practising or looking to move into the biomaterials field, undergraduate and post graduate students and those conducting bio-related research in either academia or industry. It will prove useful to mechanical engineers, biotechnologists, biomechanical engineers, metallurgists, clinicians and even surgeons.

This book starts with concepts of bone, its structure, remodelling, materials for implants and implant testing methods. Calcium phosphate ceramics and need for titanium surface modification are detailed in the initial chapters. Surface modification techniques include plasma spraying, sol-gel, biomimetic, electrochemical, laser, sputtering and ion-implantation methods. Chapters 5 to 19 deal with these modification techniques. Chapters 20-22 deal with less-common methods titanium nitride coating, protein modification, diamond like carbon coating and ultraviolet treatment. Substituting the apatite lattice with other cations like silicon, magnesium, sodium, carbon, etc is provided. The chapters involving these techniques begin with a small introduction about that technique and go on to explain the underlying principles, methodology and properties of the coats. According to the authors, the book gives a complete overview of almost all the surface modification techniques known, as applied to titanium biomaterials.

Biotechnology has the potential to improve people’s quality of life and holds the key to many unmet clinical needs. In the UK alone the biotechnology market is worth £4.5 billion and estimates of future growth range from 10 to 15%. This growth can only be driven by the increased use of inexpensive and easy to manufacture polymeric biomaterials. Although polymer science is a rapidly developing area of research, it remains that one of the most intractable problems encountered in biotechnology is that the performance of polymeric biomaterials depend upon both the bulk and surface properties. In this book the authors describe their work using lasers to modify the wettability characteristics of nylon 6,6 (as wetting is often the primary factor dictating the adhesion and bonding potential of materials) as a route to enhancing the surface in terms of in vitro osteoblast cell response. What is more, modifying wettability characteristics in this way is shown to be a highly attractive means of estimating the biofunctionality of a polymer. The book demonstrates and explains how the generation of a biomimetic surface on polymers using laser beams provides an in vitro platform on which to deposit and grow cells for either the development of implants or to reconstitute functional tissue. The correlative trends and generic characteristics which are identified in the book between the laser surface treatment, wettability characteristics and osteoblast cell response of the nylon 6,6 provide a means to estimate the osteoblast cell response in vivo. The book shows clearly that laser surface modification of polymeric materials has tremendous potential for application within the field of regenerative medicine.

The surface modification of biomaterials plays a significant role in determining the outcome of biological-material interactions. With the appropriate modification a material’s surface can be tailored to improve biocompatibility, adhesion and cell interactions. Consequently surface modification is vital in the development and design of new biomaterials and medical devices. Surface modification of biomaterials reviews both established surface modifications and those still in the early stages of research and discusses how they can be used to optimise biological interactions and enhance clinical performance. Part one begins with chapters looking at various types and techniques of surface modification including plasma polymerisation, covalent binding of poly (ethylene glycol) (PEG), heparinisation, peptide functionalisation and calcium phosphate deposition before going on to examine metal surface oxidation and biomaterial surface topography to control cellular response with particular reference to technologies, cell behaviour and biomedical applications. Part two studies the analytical techniques and applications of surface modification with chapters on analysing biomaterial surface chemistry, surface structure, morphology and topography before moving onto discuss modifying biomaterial surfaces to optimise interactions with blood, control infection, optimise interactions with soft tissues, repair and regenerate nerve cells, control stem cell growth and differentiation and to optimise interactions with bone. The distinguished editor and international team of contributors to Surface modification of biomaterials have produced a unique overview and detailed chapters on a range of surface modification techniques which will provide an excellent resource for biomaterials researchers and scientists and engineers concerned with improving the properties of biomaterials. It will also be beneficial for academics researching surface modification. Reviews both established surface modifications and those still in the early stages of research and how they can be used to optimise biological interactions and enhance clinical performance Studies analytical techniques and applications of surface modification with chapters assessing biomaterial surface chemistry, surface structure, morphology and topography Discusses modifying biomaterial surfaces to optimise interactions with blood and soft tissues and also to repair and regenerate nerve cells and control infection
