We outline a basic strategy of how self-propulsion can be used to improve the yield of a typical colloidal self-assembly process. The success of this approach is predicated on the thoughtful design of the colloidal building block as well as how self-propulsion is endowed to the particle. As long as a set of criteria are satisfied, it is possible to significantly increase the rate of self-assembly, and greatly expand the window in parameter space where self-assembly can occur. In addition, we show that by tuning the relative on-off time of the self-propelling force it is possible to modulate the effective speed of the colloids allowing for further optimization of the self-assembly process.
我们概述了一种基本策略，即如何利用自推进来提高典型胶体自组装过程的产率。这种方法的成功取决于胶体构建单元的精心设计以及如何赋予粒子自推进能力。只要满足一组标准，就有可能显著提高自组装速率，并大大扩展自组装能够发生的参数空间窗口。此外，我们表明，通过调整自推进力的相对开启-关闭时间，可以调节胶体的有效速度，从而进一步优化自组装过程。
