Stress and Strain
• Extension for a given load varies with geometry and composition
• Normalization of load and deformation to allow comparison of different materials

• Surface properties direct the biological response
• Not toxicology • Mechanical and functional design,
while critical, are not central to biocompatibility
• Blood vessels play a crucial role in tissue growth by providing nutrients, a means for waste removal and a supply of additional cells
• Nervous system is responsible for the integration and control of all of the bodies functions

Biomaterials Science
• Physical and biological study of materials and their interaction with the biological environment
– Synthesis – Optimization – Testing – Biology of host-material interactions
