类似于原子-分子关系，具有确定的组成和方向键的纳米颗粒（NP）簇（或NP-分子）可以潜在地整合组分单个NP的性质，从而导致涌现的性质。尽管在这个方向上进行了广泛的努力，但没有通用的方法可用于组装这样的NP分子。在这里，我们报告了一个一般的方法，通过封装到自组装DNA多面体线框纳米笼，作为进一步组装的指导剂，纳米粒子的这种类型的结构。作为示范，一系列NP-分子已被组装和验证。我们相信，这种NP分子将为探索具有与单个组分纳米颗粒相关但不属于单个组分纳米颗粒的新兴功能/性质的新纳米材料铺平道路。
Analogous to the atom-molecule relationship, nanoparticle (NP) clusters (or NP-molecules) with defined compositions and directional bonds could potentially integrate the properties of the component individual NPs, leading to emergent properties. Despite extensive efforts in this direction, no general approach is available for assembly of such NP-molecules. Here we report a general method for building this type of structures by encapsulating NPs into self-assembled DNA polyhedral wireframe nanocages, which serve as guiding agents for further assembly. As a demonstration, a series of NP-molecules have been assembled and validated. Such NP-molecules will, we believe, pave a way to explore new nanomaterials with emergent functions/properties that are related to, but do not belong to the individual component nanoparticles.
