Laser Surface Treatment of Bio-Implant Materials


Book Description

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.




Laser surface treatment of a polymeric biomaterial:


Book Description

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.

Surface Coating and Modification of Metallic Biomaterials


Book Description

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.
