Abstract
Dendron-stabilized gold nanoparticles synthesized with Fréchet-type dendrons possessing a single thiol group at the focal point have small cores (average diameters of 2.4–3.1 nm) with narrow size distribution and remarkably high stability; in particular, the nanoparticles synthesized with the second generation dendron has an almost monodisperse core (2.4 ± 0.2 nm).
