Using DNA molds for templating nanoparticles into 2D patterns

DNA nanotechnology employs DNA as a programmable building material for self-assembled, nanoscale structures with precisely controlled structures, that can lead to improved surface properties relevant to biosensing, materials science, and cell biology. Adding to the available tools for DNA nanopatterning, researchers have demonstrated a novel biotemplating strategy for ordering various nanoparticles into expected two-dimensional (2D) patterns via nanoparticle-surface or nanoparticle-DNA interaction.
