Book excerpt: This book provides a comprehensive overview of the latest advances in a wide range of biomaterials for the development of smart and advanced functional materials. It discusses the fundamentals of bio-interfacial interactions and the surface engineering of emerging biomaterials like metals and alloys, polymers, ceramics, and composites/nanocomposites. In turn, the book addresses the latest techniques and approaches to engineering material surfaces/interfaces in, e.g., implants, tissue engineering, drug delivery, antifouling, and dentistry. Lastly, it summarizes various challenges in the design and development of novel biomaterials. Given its scope, it offers a valuable source of information for students, academics, physicians and particularly researchers from diverse disciplines such as material science and engineering, polymer engineering, biotechnology, bioengineering, chemistry, chemical engineering, nanotechnology, and biomedical engineering for various commercial and scientific applications.
