2. Introduction to Bio-material Polymer Technology

What is the definition of a biomaterial?

• Any substance that has been engineered to interact with non-biological systems

• Any material, natural or man-made, that comprises a living structure

• Any substance engineered to interact with biological systems for a medical purpose

• Any material used to make devices to replace a part of the body

Which type of polymers are artificially produced in laboratories?

• Biodegradable polymers

• Synthetic polymers
