ABSTRACT
Bioinspired peptides are attractive biomolecules which can improve our understanding of self-assembly processes for rational design of new peptide-based materials. Herein, a new amidated peptide FRSAPFIE (FRS), based on a sequence present in human collagen, was synthesized, characterized by mass spectrometry and subjected to self-assembling investigations. The optimal conditions for self-assembly were disclosed by dynamic light scattering at 32 °C and a peptide concentration of 0.51 %. In addition, AFM studies revealed ellipsoidal FRS shapes with an area between 0.8 and 3.1â
µm2 . The ability of self-assembly was also proved using FAD dye as extrinsic fluorescence reporter. According to the theoretical analysis, the FRS peptide tends to form a bundle-type association, with a type of fibrillary tangles particle. Altogether, our findings address new challenges regarding the FRS peptide which can be used in further self-assembly studies to design biocompatible drug-delivery platforms.
