EFFICIENT LIGAND EXCHANGE OF A DETERGENT BILAYER ON THE SURFACE OF METAL NANOPARTICLES FOR MOLECULAR FUNCTIONALIZATION AND ASSEMBLY, CORRESPONDING FUNCTIONALIZED NANOPARTICLES AND NANOPARTICLE ASSEMBLIES, AND THEIR USE IN PLASMONIC APPLICATIONS INCLUDING SURFACE-ENHANCED RAMAN SPECTROSCOPY

摘要

The present invention relates to a method allowing a particularly efficient ligand exchange of a detergent bilayer on the surface of metal nanoparticles for molecular functionalization and assembly, and corresponding functionalized nanoparticles and nanoparticle assemblies that can be prepared using this method, as illustrated in Figure 16, as well as their use, e.g., for piasmonic applications such as surface-enhanced Raman scattering (SERS). In particular, the invention provides corresponding methods for preparing a dimeric nanoparticle assembly, a core-satellite nanoparticle assembly, and a functionalized nanoparticle, respectively.
