Biomaterial is any matter,
surface, or device that interacts with biological systems. The study of
biomaterials has experienced steady growth over the last five decades, with
many companies investing large amounts of money into the development of new
products. Biomaterials science encompasses elements of medicine,
tissue engineering and materials
Biomaterials can be derived
either from nature or synthesized in the laboratory using a variety of chemical
approaches utilizing metallic, ceramics or polymeric constituents. They are often used and/or
adapted for a medical application, and thus comprise whole or part of a living
structure or biomedical device which performs, augments, or replaces a natural
function. Such functions may be benign, like being used for a heart valve,
or may be bioactive
with a more interactive functionality such as hydroxyapatite
coated hip implants.
Biomaterials are also used every day in dental applications, surgery, and drug
delivery. For example, a device with impregnated pharmaceutical products can be
placed into the body, which permits the prolonged release of a drug over an
extended period of time. A biomaterial may also be an autograft,
used as a transplant material.
