| Abstract: | Nanoparticles (NPs) have been studied for several decades, and outstanding advancements have been made involving fabrication methods and various properties for many different applications. NP assemblies exhibit collective properties that are superior to the properties of individual NPs, and their assembly behavior is significantly affected by interparticle interactions and surrounding layers. The temporal/spatial regulation of NPs and the active species present in NP systems are crucial for achieving desirable performances. Here, the interparticle interactions, surrounding materials (especially ligands), and temporal and spatial regulation are the main topics discussed. The principles and classical examples of these regulation strategies are provided, and the resulting NPs regulated by these strategies exhibit remarkable properties and have great potential for various applications. Finally, the future prospects of the NPs are outlined with respect to the surface modification, temporal and spatial regulation, as well as the binary cooperative complementary principle. |
