Design Principles
"Material properties are a direct consequence of molecular structure; by controlling molecular sequence, macroscopic material behavior can be precisely engineered."
This approach allows for the development of biomaterials that can mimic natural tissue mechanics, leading to improved integration and performance in medical devices and regenerative medicine. Understanding these structure-property relationships is crucial for designing materials that meet specific functional requirements.
What This Means for Your Design
By changing the building blocks (amino acids) of a protein, you can change how a gel made from that protein behaves, making it stronger, more flexible, or able to repair itself.
