Gold Superstructures: Size‐Controlled Peptide‐Directed Synthesis of Hollow Spherical Gold Nanoparticle Superstructures (Small 14/2011)

The frontispiece image shows hollow spherical assemblies of nanoparticles arising from mixtures of metal salts, simple buffers, and carefully designed peptides. The structures are prepared in aqueous conditions at neutral pH. Importantly, small modifications of the peptide sequence leads to dramatic differences in the diameter of the nanoparticle superstructures, allowing one to construct either sub-50-nm hollow spherical structures or larger (>100 nm) hollow spherical structures. For more information, please read the Communication “Size-Controlled Peptide-Directed Synthesis of Hollow Spherical Gold Nanoparticle Superstructures” by N. L. Rosi and co-workers, beginning on page 1938.
