Definition of biomaterials

The term biomaterials we use here is defined as materials in direct contact with biological systems. The minimum requirement for a biomaterial is that it must not damage the biomolecules or cells, for example of an organism. This is called biocompatibility. In the development of modern biomaterials, besides biocompatibility a central role is played by biofunctionality.

Applications of these biomaterials range from dentures to suture and wound dressing material, from stents to contact lenses and from substrate material for the in vitro cultivation of cells to replacement materials for joints, bones and soft tissue.

A wide variety of materials is suitable to be used as biomaterials (inorganic, (bio)polymer, metals, composites).
