Researchers are creating new moiré materials at the nanometer scale using advanced DNA nanotechnology. DNA moiré superlattices form when two periodic DNA lattices are overlaid with a slight rotational twist or positional offset. This creates a new, larger interference pattern with completely different physical properties. A new approach developed by researchers at the University of Stuttgart and the Max Planck Institute for Solid State Research not only facilitates the complex construction of these superlattices; it also unlocks entirely new design possibilities at the nanoscale. The study has been published in the journal Nature Nanotechnology.
