The current state of the art in the use of colloidal methods to form nanoparticle assemblies, or clusters (NPCs) is reviewed. The focus is on the two-step approach, which exploits the advantages of bottom-up wet chemical NP synthesis procedures, with subsequent colloidal destabilization to trigger assembly in a controlled manner. Recent successes in the application of functional NPCs with enhanced emergent collective properties for a wide range of applications, including in biomedical detection, surface enhanced Raman scattering (SERS) enhancement, photocatalysis, and light harvesting, are highlighted. The role of the NP-NP interactions in the formation of monodisperse ordered clusters is described and the different assembly processes from a wide range of literature sources are classified according to the nature of the perturbation from the initial equilibrium state (dispersed NPs). Finally, the future for the field and the anticipated role of computational approaches in developing next-generation functional NPCs are briefly discussed.

“…The carboxylic acid enriched nanospheres were successfully prepared and characterized by TEM. As shown in Figure 3, with the reported method, [29] the short CdS nanorods have been assembled into 100-nm nanospheres (Figure 3 a). A TEM image of the polymer-coated nanospheres prepared, using the modified encapsulation strategy, is also shown in Figure 3 b.…”

“…Such compositional diversity reveals the formation of quasicrystalline-like assemblies is a common phenomenon in nature, which is believed to attribute to the driving force of entropy and strong interparticle interaction. Our group discovered a simple and facile microemulsion-based approach for the synthesis of a wide variety of colloidal spheres with different sizes, shapes, and properties by using dispersible NCs [454]. Moreover, other types of NPs such as semiconducting metal chalcogenides, metal oxides, and rare-earth compounds with the hydrophobic ligands on the surface can serve as the building blocks by taking advantage of the oil-in-water (O/W) microemulsion system.…”

This review covers the major reactions involved in the solution synthesis of nanomaterials. It was designed to classify the traditional strategies such as precipitation, reduction, seed growth, etching, and so on into two basic processes which are termed as bottom-up and top-down routines. The discussion is focused on the basic mechanism and principles during the nucleation and growth of nanocrystals, especially in the solution system. This review also presents a prediction for how to utilize these intrinsic processes to artificially construct the desired specific and functional nanostructures. We try to describe the most directive and effective way to control the structures of nanocrystals for researchers who can master the major reaction mechanism and grasp the basic technologies in synthetic nanoscience.
