摘要：

Hollow spherical gold nanoparticle superstructures with tunable diameters (similar to 40 nm, similar to 70 nm and similar to 150 nm) and visible to near-infrared surface plasmon resonances (545 nm, 670 nm, and 740 nm) are prepared using a single peptide conjugate, C-6-AA-PEPAu, as the structure-directing agent. Computational models are developed to understand their optical properties.
