This book gives a comprehensive overview of surface modifications for applications in biotechnology using intelligent coatings from metals to plastics, including materials chemical properties, characterization methods, coating techniques, state-of-the-art examples, and an outlook on the promising future of this technology. It enables the interested materials scientist, chemist, or engineer to gain a comprehensive overview of the field, highlighting applications of high-impact, with each chapter being written by an expert in that particular area. Applications will include tissue engineering, biotribology, drug targeting and delivery, wound healing, biosensors, nanopatterning, and bioinspired design of new smart materials and surfaces.
H. Michelle Grandin currently works as a scientific writer and consultant in the field of tissue regeneration and implant surfaces for dental applications. Previously, she worked as a senior research scientist in the biointerface group of Marcus Textor at ETH Zurich. There, she developed a waveguide fluorescence microscope for the study of bio-interactions in the near-field as well as leading a group in the development of 3D single cellular microwell arrays for application in stem cell and cancer research.
Marcus Textor is a Professor Emeritus at ETH Zurich, Department of Materials. He was head of a research group dedicated to surfaces and interfaces in bio-related fields of material science. His research interests cover both fundamental aspects of the behavior of materials in contact with biological milieus and the design and development of surfaces that elicit biospecific responses.
