Novel dendron-stabilized gold nanoparticles with high stability and narrow size distribution

Dendron-stabilized gold nanoparticles synthesized with Frechet-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).
