定制的聚合物壳驱动所需类别的纳米颗粒结构的组装从纳米颗粒合成的早期开始，研究人员就了解到需要适应性强的方法来协调具有精确纳米结构的簇中的颗粒。从粒子构建纳米级簇与从原子形成分子之间的相似性超出了结构类比。与分子一样，其表现出在原子中未发现的性质，簇表现出超出单个纳米颗粒性质的协同功能响应（1 - 3）。对于原子系统，分子的形成是合理的轨道杂化原理。由于这一概念不适用于纳米粒子，科学家们探索了其他粒子组装方法。在本期的第1369页，Yi等人（4）描述了一种用于组装靶向纳米颗粒簇的高产率方法。
Tailored polymer shells drive the assembly of a desired class of nanoparticle architectures From the early days of nanoparticle synthesis, researchers understood the need for adaptable methods that coordinated particles in clusters with precise nanoarchitecture. The similarity between the building of nanoscale clusters from particles and the formation of molecules from atoms goes beyond a structural analogy. As with molecules, which demonstrate properties not found in atoms, clusters exhibit synergistic functional responses beyond the properties of individual nanoparticles (1–3). For atomic systems, the formation of molecules is rationalized by orbital hybridization principles. Because this concept is not suitable for nanoparticles, scientists have explored other particle-assembly methods. On page 1369 of this issue, Yi et al. (4) describe a high-yield method for the assembly of targeted nanoparticle clusters.
