Biomaterials

Introduction

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, biology, chemistry, tissue engineering and materials science.​

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, allograft or xenograft used as a transplant material.
