Peptide Nanotubes: Simple Separation Using Size‐Exclusion Columns and Use as Templates for Fabricating One‐Dimensional Single Chains of Au Nanoparticles

Straight single chains of Au nanoparticles have been synthesized using 10 nm diameter peptide nanotubes as templates (see Figure). The 6 nm Au nanoparticles grow in the gaps between the synthetic peptide coating the nanotubes which regulates the size, dispersity, interparticle distance, and crystallinity of the nanoparticles. The use of longer nanotubes results in longer chains.
