(A) Molecular models of RADA-RGD, RADA-TTS, RADA-FOG and RADA16. Atoms are colored by atom type (C, white; N blue; O, red; H gray). (B) Schematic model of a self-assembling nanofiber with ligand TTSWSQ (1:1). the designer peptides folded into amphiphilic β-sheets which stacked into a bilayer structure with a hydrophobic core. The incorporating sequences were extending out from the nanofibers.
