Abstract
Methods for synthesizing nanowires are provided. Modified PilA peptides are used as peptide building blocks for synthesizing the nanowires. The method places the peptide building blocks in an assembly buffer with a hydrophobe. Addition of a hydrophobe and molecular crowding by evaporation of the assembly buffer triggers the self-assembly of the peptide building blocks into fibers. Multiple elongation cycles of addition of peptide building blocks, mixing and evaporation are conducted to promote elongation of the fibers and synthesis of nanowires. Electronic characterization of the synthesized nanowires is provided.
