Micro construction sites : Engineered peptides and ligand‐functionalized gold nanoparticles have been assembled into micrometer‐scale 3D cube‐shaped crystals (see picture), creating a physical framework for a biomimetic assembly strategy. The NPs join the peptide nanowires through streptavidin–biotin interactions to create cubic unit cells.
