One-step seeded growth of Au nanoparticles with widely tunable sizes

A one-step seeded growth process has been developed for the synthesis of Au nanoparticles with tunable diameters from ∼10 nm to ∼200 nm. The delicately designed growth system suppresses self-nucleation by stabilizing a concentrated growth solution with strong coordinating ligands, leading to precise size control and convenient, scalable fabrication of Au nanoparticles.
