A comprehensive guide to the science of a transformational ultrananocrystalline-diamond (UNCDTM) thin film technology enabling a new generation of high-tech and external and implantable medical devices. Edited and co-authored by a co-originator and pioneer in the field, it describes the synthesis and material properties of UNCDTM coatings and multifunctional oxide/nitride thin films and nanoparticles, and how these technologies can be integrated into the development of implantable and external medical devices and treatments of human biological conditions. Bringing together contributions from experts around the world, it covers a range of clinical applications, including ocular implants, glaucoma treatment devices, implantable prostheses, scaffolds for stem cell growth and differentiation, Li-ion batteries for defibrillators and pacemakers, and drug delivery and sensor devices. Technology transfer and regulatory issues are also covered. This is essential reading for researchers, engineers and practitioners in the field of high-tech and medical device technologies across materials science and biomedical engineering.
