Biomedical Engineering Theory And Practice/Biomaterials/Introduction to biomaterials
The United States National Institute of Health Consensus Development Conference defined a biomaterial as ‘‘Any substance (other than a drug) or combination of substances, synthetic or natural in origin, which can be used for any period of time, as a whole or as a part of a system which treats, augments, or replaces any tissue, organ, or function of the body’’ (Boretos and Eden, 1984). Biomaterials area has grown over for 50 years. Biomaterils as a field uses ideas from medicine, biology, chemistry, materials science and engineering. In addition, biomaterials researchers should consider ethics,law and the health care delivery system.
Biomaterials can be divided into metals, ceramics, polymers, glasses, carbons, and composite materials. Such materials are used as molded or machined parts, coatings, fibers, films, foams,fabrics,liquid and powder.
