Self-assembly of nanoparticles has emerged as a powerful technique to integrate nanoparticlesinto well-defined ensembles with collective properties that are different from those of individualnanoparticles and bulk materials with the same chemical composition. Compared with theclassical ion/molecule-mediated crystal growth, particle-mediated crystallographically orderedself-assembly is considered as ‘‘non-classical crystallization’’ and the resultant product is termed a‘‘mesocrystal’’. In this tutorial review, we begin by summarizing the progresses of this field duringlast decade. Secondly, we outline developments in related fields such as grairotation andoriented attachment as well as mesocrystals. Thridly, the recent progress in the syntheses ofmesocrystals particularly in metals, and the related properties are introduced. Finally, some of thecurrent open questions are discussed.![]()
