Biological tissues rich in type I collagen exhibit specific hierarchical fibrillar structures together with remarkable mechanical toughness. However, the role of collagen alone in their mechanical response at different structural levels is not fully understood. Here, it is proposed to rationalize such challenging interplay from a materials science perspective through the subtle control of this protein...
Extracellular matrices (ECM) rich in type I collagen exhibit characteristic anisotropic ultrastructures. Nevertheless, working in vitro with this biomacromolecule remains challenging. When processed, denaturation of the collagen molecule is easily induced in vitro avoiding proper fibril self‐assembly and further hierarchical order. Here, an innovative approach enables the production of highly concentrated...
In article number 1902224, Bernard Coulomb, Nadine Nassif, and co‐workers propose an innovative spray‐processing approach, allowing fast and cheap production of highly concentrated, self‐assembled type I collagen microparticles. The native properties of collagen are preserved, further enabling the encapsulation of therapeutic biomolecules and their injection for potential active tissue regeneration...
Affinity‐triggered assemblies rely on affinity interactions as the driving force to assemble physically crosslinked networks. WW domains are small hydrophobic proteins binding to proline‐rich peptides that are typically produced in the insoluble form. Previous works attempted the biological production of the full WW domain in tandem to generate multivalent components for affinity‐triggered hydrogels...
