Size-Controlled Peptide-Directed Synthesis of Hollow Spherical Gold Nanoparticle Superstructures

Size-Controlled Peptide-Directed Synthesis of Hollow Spherical Gold Nanoparticle Superstructures

Choose your favorite size: Peptide conjugates, BP–Ax–PEPAu, 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 l...

Zusammenfassung:Choose your favorite size: Peptide conjugates, BP–Ax–PEPAu, 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.
