Nature Communications (May 15): Crystalline Mesoporous Frameworks Self-Assembled From Amphiphilic Collagen-Mimetic Peptides Open New Biomaterials Route
A Nature Communications paper details crystalline mesoporous frameworks built from amphiphilic collagen-mimetic peptides (aCMPs) — charge-segregated collagen-mimetic sequences modified with lipid tails at their N-termini. Hydrophobic and electrostatic interactions drive 3D porous architectures whose lattice packing tracks with lipid-tail length (C12, C10, C8); shortening to C6 flips assembly into nanosheets. The work expands peptide-based biomaterials beyond the triple helix and offers a programmable scaffold platform for drug delivery and tissue engineering.
