Controlled high-yield assembly of gold nanoparticles via amide bond formation
Abstract
-AuNPs and COOH-AuNPs form covalently linked assemblies with yields of 95 ± 5%. The resulting nanoassemblies exhibit well-defined 1 : 1 or 1 : 2 core-satellite stoichiometries, reflecting the limited availability of activated carboxyl groups. Raman spectroscopy confirms the formation of interparticle amide bonds. Finally, we demonstrate that this method is broadly applicable to the high-yield assembly of AuNPs across diverse shapes (nanospheres, nanocubes, nanorods) and sizes (14-101 nm). This strategy provides a versatile platform for constructing plasmonic nanoassemblies with chemical reactions.
