Nanoparticle Assemblies: Nanoparticle Clusters: Assembly and Control Over Internal Order, Current Capabilities, and Future Potential (Adv. Mater. 27/2016).

Clusters or assemblies of nanoparticles exhibit unique features which arise from the enhancement of properties of single nanoparticles or due to new collective properties. On page 5400, D. F. Brougham and co-workers review the role of nanoparticle interactions in controlling cluster formation, and classify the assembly mechanisms. Emerging applications for surface-enhanced Raman scattering (SERS), optical labeling, light harvesting, magnetic resonance imaging (MRI), hyperthermia, photocatalysis, enrichment, and separation are presented.
