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 tile. The center-to-center interparticle spacing between neighboring particles is controlled to be approximately 38 nm. These evenly distributed Au NP arrangements with accurate control of interparticle spacing may find applications in nanoelectronic and nanophotonic devices.
我们报道了使用自组装二维（2D）DNA纳米网格作为模板，将5纳米金纳米颗粒（Au NPs）组织成周期性方形晶格。每个颗粒仅位于单个DNA瓦片上。相邻颗粒之间的中心距被控制为约38纳米。这些具有精确颗粒间距控制的均匀分布的金纳米颗粒排列可能在纳米电子和纳米光子器件中找到应用。
