Just as nanoparticles display properties that differ from those of bulk samples of the same material, ensembles of nanoparticles can have collective properties that are different to those displayed by individual nanoparticles and bulk samples. Self-assembly has emerged as a powerful technique for controlling the structure and properties of ensembles of inorganic nanoparticles. Here we review different strategies for nanoparticle self-assembly, the properties of self-assembled structures of nanoparticles, and potential applications of such structures. Many of these properties and possible applications rely on our ability to control the interactions between the electronic, magnetic and optical properties of the individual nanoparticles.
正如纳米粒子显示出与同一种材料的块状样品不同的性质一样，纳米粒子的集合体也可以具有不同于单个纳米粒子和块状样品的集体性质。自组装已成为控制无机纳米粒子集合体结构和性质的一种强大技术。在这里，我们回顾了纳米粒子自组装的不同策略、纳米粒子自组装结构的性质以及这种结构的潜在应用。这些性质和可能的应用中的许多都依赖于我们控制单个纳米粒子的电子、磁性和光学性质之间相互作用的能力。
