Molecular model21 of the G4-K-G4 peptide over a crystalline PLA surface in 140-mM TIP3P saline prior to simulation. The PLA surface is shown as a wireframe model with hydrogen atoms omitted for clarity; the peptide, Na+, and Cl− ions (silver and gold, respectively) are shown as space-filled atoms with their van der Waals radii; and water molecules are shown as dots. (a) An axial view of the surface polymer chains (view along the z axis). (b) View following 270° rotation about the vertical axis (view along the x axis). Peptide is shown with an SSD value of 15 Å.
