One of the frontiers of nanotechnology is advancing beyond the periodic self-assembly of materials. Icosahedral quasicrystals, aperiodic in all directions, represent one of the most challenging targets that has yet to be experimentally realized at the colloidal scale. Previous attempts have required meticulous human-designed building blocks and often resulted in interactions beyond the current experimental capabilities. In this work, we introduce a framework for generating experimentally accessible designs that self-assemble into quasicrystalline arrangements. We present a design for icosahedral deoxyribonucleic acid (DNA) origami building blocks and demonstrate, through molecular simulations, their successful assembly into a target quasicrystalline structure. Our results highlight the feasibility of using automated design protocols to achieve complex quasicrystalline patterns, with applications in material science and nanotechnology.
纳米技术的前沿领域之一是超越材料的周期性自组装。二十面体准晶体在各个方向上都是非周期性的,是胶体尺度上尚未通过实验实现的最具挑战性的目标之一。先前的尝试需要精心设计的人工构建块,并且常常导致超出当前实验能力的相互作用。在这项工作中,我们引入了一个框架,用于生成可通过实验获得的设计,使其自组装成准晶排列。我们提出了一种二十面体脱氧核糖核酸(DNA)折纸构建块的设计,并通过分子模拟证明了它们成功组装成目标准晶结构。我们的结果突出了使用自动化设计方案实现复杂准晶图案的可行性,这在材料科学和纳米技术中具有应用价值。
