✦ Synopsis

This review focuses on the self-assembly of macromolecules mediated by the biorecognition of peptide/protein domains. Structures forming a-helices and b-sheets have been used to mediate self-assembly into hydrogels of peptides, reactive copolymers and peptide motifs, block copolymers, and graft copolymers. Structural factors governing the self-assembly of these molecules into precisely defined three-dimensional structures (hydrogels) are reviewed. The incorporation of peptide motifs into hybrid systems, composed of synthetic and natural macromolecules, enhances design opportunities for new biomaterials when compared to individual components.

Hydrogels can be composed of natural or synthetic polymers. They form a three-dimensional (3D) scaffold that can absorb a large quantity of water (>99% by volume). They can mimic the extracellular matrix, having good biocompatible and biodegradable qualities, which enables them to support the growth
