Substrate-facilitated assembly of elastin-like peptides: studies by variable-temperature in situ atomic force microscopy.
Extended duration in situ variable-temperature atomic force microscopy performed on a series of coacervating hydrophobic peptides based on human elastin revealed a novel multistage surface assembly process. Formation of epitaxially arranged peptide rods was preceded by rapid expansion of a two-dimensional film on the nucleating substrate, a process facilitated by specific hydrophobic peptide-substrate and intrapeptide interactions.
