Here, we have developed a new methodology to obtain a pure population of well-defined and new kinetically trapped structures directly in water, inaccessible by other self-assembly techniques. We have exemplified this method through the synthesis of stacked toroidal micelles trapped into a nanorattle with multiple and orthogonal surface chemical functionality. These unique polymer nanorattles result from a water-surrounded inner core (or yolk) of stacked toroidal micelles encapsulated by a shell of stacked toroids. The nanorattles were monodispersed and could be freeze-dried and rehydrated without a change in the nanorattle structure. Confirmation of the kinetically trapped nanorattle structure was through the release of the individual stacked toroids using a plasticizer. Our approach provides a strategy for the synthesis of unique nanostructures that have the potential to be coupled with biological molecules and probes capable of performing multiple tasks and functions.

堆叠环形纳米机器人的温度导向组装

在这里，我们开发了一种新方法，可以直接在水中获得明确定义和新的动力学捕获结构的纯种群，这是其他自组装技术无法获得的。我们通过合成堆叠的环形胶束来举例说明这种方法，这些胶束被困在具有多重和正交表面化学功能的 nanorattle 中。这些独特的聚合物纳米颗粒是由堆叠的环形胶束的水包围内核（或蛋黄）产生的，该胶束由堆叠的环形外壳封装。纳米颗粒是单分散的，可以在不改变纳米颗粒结构的情况下冷冻干燥和再水化。动力学捕获的 nanorattle 结构的确认是通过使用增塑剂释放单个堆叠的环形。
