Biominerals are unique materials found in many living organisms that often display outstanding functionalities attributed to their mesocrystalline structure. Mesocrystals are nanocrystal superstructures with mutual crystallographic alignment of the building units. One could thus imagine these optimized evolutionary systems as archetypes to fabricate advanced materials. The main advantage of such systems relies on their ability to combine the features of the nanocrystals with those of single crystalline microscopic structures, yielding assemblies with directional, enhanced, and potentially emergent properties. Moreover, fueled by the promises of multifunctional materials with unprecedented and tunable properties, the rational design of mesocrystals assembled from two distinct colloidal nanocrystal ensembles has become a recent focus of research. However, the combination of dissimilar nanocrystals into ordered binary superstructures is still a major scientific challenge due to the nature of the coassembly process.

胶体纳米晶体自组装成 3D 二元介晶

生物矿物是在许多活生物体中发现的独特材料，它们通常显示出归因于其介晶结构的出色功能。介晶是具有结构单元的相互晶体排列的纳米晶体超结构。因此，人们可以将这些优化的进化系统想象为制造先进材料的原型。这种系统的主要优势在于它们能够将纳米晶体的特征与单晶微观结构的特征相结合，从而产生具有定向、增强和潜在涌现特性的组件。此外，在具有前所未有和可调特性的多功能材料前景的推动下，由两种不同的胶体纳米晶体集合组装而成的介晶的合理设计已成为最近的研究重点。
