Over the last three decades, colloidal crystallization has provided an easy-to-craft platform for mesoscale engineering of photonic and phononic crystals. Nevertheless, the crystal lattices achieved thus far with commodity colloids are largely limited to symmetric and densely packed structures, restricting their functionalities. To obtain non-close-packed crystals and the resulting complexity of the available structures, directional binding between "patchy" colloids has been pursued. However, the conventional "patchy" colloids have been restricted to micrometer-scale spherical particles or clusters. In this Mini-Review, we argue that the time has come to widen the scope of the colloidal palette and include particles made using DNA origami. By benefiting from its unprecedented ability to control nanoscale shapes and patch placement and incorporate various nanomaterials, DNA origami enables novel engineering of colloidal crystallization, particularly for photonic and phononic applications. This mini-review summarizes the recent progress on using DNA origami for colloidal crystallization, together with its challenges and opportunities.
在过去三十年中，胶体结晶为光子晶体和声子晶体的中尺度工程提供了一个易于构建的平台。然而，迄今为止用商品胶体实现的晶格在很大程度上限于对称且密集堆积的结构，限制了它们的功能。为了获得非紧密堆积晶体以及由此产生的可用结构的复杂性，人们一直在探索“补丁”胶体之间的定向结合。然而，传统的“补丁”胶体仅限于微米级的球形颗粒或团簇。在本综述中，我们认为现在是时候拓宽胶体调色板的范围，将使用DNA折纸制成的颗粒包括在内了。得益于其前所未有的控制纳米级形状和补丁放置以及整合各种纳米材料的能力，DNA折纸能够实现胶体结晶的新型工程设计，特别是用于光子和声子应用。本综述总结了使用DNA折纸进行胶体结晶的最新进展，以及其面临的挑战和机遇。
