基于模块化DNA瓦片的自组装是一种在纳米尺度上设计基本镶嵌图案的通用方法,但要实现高水平的结构复杂性仍然具有挑战性。我们介绍了一套通用的设计原则,通过采用低对称性的多臂DNA基序来创建复杂的DNA镶嵌。我们实现了两个新的阿基米德镶嵌模式,(4.8.8)和(3.6.3.6),以及一个具有高阶结构的模式,其复杂性超出了阿基米德镶嵌中观察到的复杂性。我们在组装复杂DNA镶嵌方面的成功展示了DNA结构基序的广阔设计空间,丰富了基于DNA瓦片的自组装工具箱,并扩展了基于DNA瓦片的镶嵌的复杂性边界。
Modular DNA tile‐based self‐assembly is a versatile way to engineer basic tessellation patterns on the nanometer scale, but it remains challenging to achieve high levels of structural complexity. We introduce a set of general design principles to create intricate DNA tessellations by employing multi‐arm DNA motifs with low symmetry. We achieved two novel Archimedean tiling patterns, (4.8.8) and (3.6.3.6), and one pattern with higher‐order structures beyond the complexity observed in Archimedean tiling. Our success in assembling complicated DNA tessellations demonstrates the broad design space of DNA structural motifs, enriching the toolbox of DNA tile‐based self‐assembly and expanding the complexity boundaries of DNA tile‐based tessellation.
