We describe a bio-inspired process to generate hierarchically defined structures with multiscale morphology by using regenerated silk fibroin.

The combination of protein self-assembly and microscale mechanical constraints is used to form oriented, porous nanofibrillar networks within predesigned macroscopic structures.

This approach allows us to predefine the mechanical and physical properties of these materials, achieved by the definition of gradients in nano- to macroscale order.
