摘要：

In this communication, we describe the covalent assembly of gold nanoparticles into core-satellite clusters using the "cream of the crop" Click reaction, namely, azide-alkyne Huisgen 1,3-dipolar cycloaddition. Surface enhanced Raman scattering (SERS), localized surface plasmon resonance (LSPR) spectroscopy, transmission electron microscopy (TEM) and dynamic light scattering (DLS) confirm the successful "Click" between the plasmonic cores and satellites.
