Abstract

Taking inspiration from seed-mediated crystal growth in atomic and molecular systems, a strategy is developed for incorporating particle and volume defects into the interior of colloidal crystals consisting of programmable atom equivalents (PAEs, oligonucleotide-functionalized nanoparticles) assembled with DNA. Discrete PAEs spanning a range of shapes, sizes, and compositions serve as nucleation sites for seed-mediated colloidal crystal growth and are incorporated into the centers of colloidal crystal lattices as cavities. Importantly, seed PAE shapes or sizes that are geometrically mismatched with the colloidal crystal lattice symmetry introduce defects such as local lattice disorder and long-range grain boundaries that arise through geometric frustration. Colloidal crystals synthesized with plasmonic seed particles exhibit near-infrared (NIR) wavelength scattering cross-sections that are highly dependent upon cavity/particle size and shape. Taken together, these findings establish a platform for the deliberate introduction of 2 and 3D defects into colloidal crystals, which may inform the design of structures and materials for thermal management, sensing, and catalysis.

用DNA工程将缺陷和空洞编程成胶体晶体。

受原子和分子系统中种子介导的晶体生长的启发，研究人员开发了一种将颗粒和体积缺陷整合到由可编程原子等效物（PAEs，寡核苷酸功能化纳米颗粒）与DNA组装的胶体晶体内部的策略。离散PAEs跨越一系列形状、大小和成分，作为种子介导的胶体晶体生长的成核位点，并作为空腔并入胶体晶体晶格的中心。重要的是，种子PAE的形状或大小在几何上与胶体晶体晶格对称不匹配会引入缺陷，如局部晶格无序和远程晶界，这些缺陷是由几何挫折引起的。由等离子体种子粒子合成的胶体晶体表现出近红外（NIR）波长散射截面，其高度依赖于腔/粒子的大小和形状。综上所述，这些发现为有意将2和3D缺陷引入胶体晶体建立了一个平台，这可能为热管理、传感和催化的结构和材料设计提供信息。
