Biomimetic crystallization for long-pursued –COOH-functionalized gold nanocluster with near-infrared phosphorescence

Recently, Professor Di Sun's group at Shandong University extended the salting-out method (commonly used to crystallize biological macromolecules, proteins, and DNA) to crystallize –COOH-functionalized AuNCs and obtained high-quality single crystals of three novel –COOH-functionalized Au25 nanoclusters, revealing the crystallographic structure of long-pursued –COOH-functionalized AuNCs.
