Nanostructured materials, including plasmonic metamaterials made from gold and silver nanoparticles, provide access to new materials properties. The assembly of nanoparticles into extended arrays can be controlled through surface functionalization and the use of increasingly sophisticated linkers. We present a versatile way to control the bonding symmetry of gold nanoparticles by wrapping them in flower-shaped DNA origami structures. These “nanoflowers” assemble into two-dimensonal gold nanoparticle lattices with symmetries that can be controlled through auxiliary DNA linker strands. Nanoflower lattices are true composites: interactions between the gold nanoparticles are mediated entirely by DNA, and the DNA origami will fold into its designed form only in the presence of the gold nanoparticles.

订购带有DNA折纸纳米花的金纳米颗粒

纳米结构材料,包括由金和银纳米颗粒制成的等离子超材料,提供了获得新材料性能的途径。纳米粒子组装成扩展阵列可以通过表面功能化和使用日益复杂的连接子来控制。我们提出了一种通用的方法,通过将它们包裹在花状DNA折纸结构中来控制金纳米颗粒的键对称性。这些“纳米花”组装成二维的金纳米粒子晶格,其对称性可以通过辅助DNA接头链来控制。纳米花晶格是真正的复合物:金纳米颗粒之间的相互作用完全由DNA介导,只有在金纳米颗粒存在的情况下,DNA折纸才会折叠成其设计形式。
