Epitaxial Growth of Peptide Nanofilaments on Inorganic Surfaces: Effects of Interfacial Hydrophobicity/Hydrophilicity

Abstract

Taking a stand: Self-assembled peptide aggregates adopt interfacial orientations in which they either lie horizontally (on highly ordered pyrolytic graphite, hydrophobic) or are oriented upright (on mica, hydrophilic) to form nanofilaments with different heights. This process is controlled by the interfacial hydrophobic or electrostatic interactions.
