摘要：

(Figure Presented) Just one click, and the color's gone: In the presence of Cu2+ with sodium ascorbate as a reductant, gold nanoparticles that have azide- and alkyne-terminated groups undergo aggregation as the result of CuI-catalyzed click chemistry. This process can be monitored by eye without the aid of instruments (NPs=nanoparticles). © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
