Choose your favorite size : Peptide conjugates, BP–A x –PEP Au , direct the synthesis and assembly of gold nanoparticles into well‐defined hollow spherical gold nanoparticle superstructures. The diameter of the superstructures can be dialed‐in by choosing the proper number of alanine residues, x : x = 2 leads to superstructures with diameters larger than 100 nm while x = 3 leads to superstructures with sub‐50‐nm diameters.
