我们报道了使用一种自组装的二维（2D）DNA纳米网格作为模板，将5纳米的金纳米粒子（Au NPs）组织成周期性的方形晶格。每个粒子仅位于单个DNA上。相邻粒子之间的中心到中心的粒子间距被控制为约38纳米。这些粒子间距得到精确控制的均匀分布的金纳米粒子排列可能在纳米电子和纳米光子器件中得到应用。
We report the use of a self-assembled two-dimensional (2D) DNA nanogrid as a template to organize 5-nm gold nanoparticles (Au NPs) into periodic square lattices. Each particle sits on only a single DNA the. The center-to-center interparticle spacing between neighboring particles is controlled to be similar to 38 nm. These evenly distributed Au NP arrangements with accurate control of interparticle spacing may find applications in nanoelectronic and nanophotonic devices.
