Biomaterials are materials of natural or synthetic origin designed to be biocompatible, meaning they can come in contact with tissues, blood plasma, or biological fluids. Their biocompatibility is important as they can be used in the production of prostheses, for diagnostic and therapeutic aims, and for storage or preservation, without adversely affecting the living organism. You will study these materials in detail, learn about their application, and how to choose the right material for a certain purpose. In the last part of the unit, you will find out how to design a new material serving a specific purpose.
