Scientists twist DNA into self-building nanostructures that could transform technology

DNA nanotechnology enables the creation of moiré superlattices at the nanometer scale. Researchers at the University of Stuttgart developed a bottom-up assembly process using DNA strands to form precisely twisted bilayers or trilayers with tunable properties. This breakthrough opens new possibilities in molecular engineering, nanophotonics, and materials science, allowing for the construction of customized 2D and 3D architectures with potential applications in spin-selective electron transport and gradient-index photonic devices.
