Abstract

L-Lysine based dendrimers containing a disulfide moiety at the core were synthesized. These novel ligands were used to stabilize Au nanoparticles via a one-phase chemical reduction method. The size of the resultant nanoparticles was found to decrease with increasing dendritic generation. Furthermore, the thermal stability of the nanoparticles in solution was shown to be controlled by the extent of branching in the protecting dendritic shell.
