摘要：

Iodine glue! Spontaneous iodine chemisorption on gold nanoparticles is demonstrated. The concomitant electron injection into gold nanoparticles results in particle fusion, fragmentation, and aggregation, excess KI addition leads to the formation of nanocrystals (see scheme). Surprisingly, iodine-glued" surfacebound nanostructured assemblies of gold nanoparticles can be constructed on an amino-functionalized solid support by stepwise derivatization with colloidal Au and KI solution."
