摘要：
The interaction of colloidal gold in aqueous solutions with L-arginine solutions of different concentrations and in various mixing ratios was investigated by UV-Vis spectroscopy, transmission electron microscopy (TEM) and atomic force microscopy (AFM). It is evidenced that L-arginine mediates the formation of assemblies of gold nanoparticles, which are shown in TEM and AFM observations to have a complex structure. The TEM results for the evolution of these assemblies are used to evidence the progress in the building process of supermolecular structures. A model is proposed for the mediating action of arginine in the interparticle interactions.
