A biomaterial is any substance that has been contrived to interact with biological systems for a medical purpose which can be therapeutic or a diagnostic one. The study of biomaterials is called biomaterials science. It is also known as biomaterials engineering. It incorporates elements of medicine, biology, chemistry, tissue engineering and materials science. It has experienced steady and strong growth over its history, with many companies investing large amounts of money into the development of new products. A biomaterial that is biocompatible or suitable for one application may not be biocompatible in another. It can be derived naturally or produced synthetically. It can be synthesized in the laboratory by utilizing components like polymers, ceramics or composite materials.
