Luminescent Biofunctional Collagen Mimetic Nanofibers.

ABSTRACT: Collagen has long been one of the top targets for biomimetic design due to its superior structural and functional properties. Significant progress has been achieved to construct self-assembling peptides to mimic the fibrous nanostructure of native collagen, while it is still very demanding to fabricate peptide assemblies that can recapitulate both structural and biofunctional features of collagen. Herein, collagen-like peptides have been synthesized to contain negatively charged amino acids as the binding groups of lanthanide ions and the integrin-binding motif GFOGER. The simultaneous inclusion of negatively charged amino acids in the middle as well as at both terminals drives the peptides to self-assemble to form well-ordered nanofibers with distinct periodic banding patterns specificall
