Water-Based Assembly and Purification of Plasmon-Coupled Gold Nanoparticle Dimers and Trimers
We describe a simple one-pot water-based scheme to produce gold nanoparticle groupings with short interparticle spacings. This approach combines a cross-linking molecule and a hydrophilic passivation layer to control the level of induced aggregation. Suspensions of dimers and trimers are readily obt...
