Caption
Structural characteristics of the self-assembled nr-YH peptide on graphite and molybdenite. (A to C) FM-AFM-recorded molecular resolution images of the self-assembled 3r-, 4r-, and 5r-YH peptides forming 2D lattices on graphite in water and that of 4r-YH on MoS2 (D). (E to H) The corresponding FFT pattern obtained from the peptide assemblies in panels (A-D). The reconstructed images in (I-L) are obtained by executing inverse 2D FFT spectra (E-H). The white arrows show bright contrast features in a given peptide lattice, the number of which is consistent with the repeating YH units for each peptide assembly. (M-P) Crystallographic orientation relationships between the peptide crystals and the solid lattice obtained through matching the molecular lattice of the peptide and the atomic lattice of the solids that give chiral relationship for each peptide. All images were recorded by in situ FM-AFM using 1.5 µM peptide solutions.
