What Are Biomaterials?
• A biological or synthetic substance which can be introduced into body
tissue as part of an implanted medical device or used to replace an
organ, bodily function, etc.
• A biomaterial is any substance that has been engineered to interact
with biological systems for a medical purpose - either a therapeutic
(treat, augment, repair or replace a tissue function of the body) or a
diagnostic one.
