Abstract

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 ∼38 nm. These evenly distributed Au NP arrangements with accurate control of interparticle spacing may find applications in nanoelectronic and nanophotonic devices.
