Introduction to Biomaterials

A Biomaterial is a Non-viable materials used in a medical devices intended to interact with biological systems. They may be distinguished from other materials in that they possess a combination of properties, including chemical, mechanical physical and biological properties that render them suitable for safe, effective and reliable use within a physiological environment.
[D.F. Williams, Jour. Mat. Sci. (23) 1987]

Put simply it is a non-living (non viable) which is intended to have close contact with biological tissue (i.e. you) which has approrriate mechanical and physiological properties for its application (i.e. meets the required strength and safety for its useage)

Biomaterials are used in many of todays medical devices, including, artifical skin, artificial blood vessels, total artificial hearts, pacemakers, dental fillings, wires plates and pins for bone repair, total artificial joint replacements.
