  text: <jats:p>In recent years, nanostructures assembled by DNA have found promising
    applications in optics, medicine, and sensing. DNA origami in particular provides
    unique self‐assembly properties, not only enabling a vast variety of functionalization
    schemes but also presenting a promising route to fabricate large‐scale, bottom‐up
    nanostructured arrays. This approach has comparable precision to electron beam
    lithography but avoids slow and expensive patterning steps. However, self‐assembly
    of lattices with high order and well‐defined periodicity requires careful tuning
    of the deposition parameters and interactions involved, which has been done mostly
    on mica so far. As mica is not compatible with standard microfabrication processes,
    we investigate here the assembly of DNA origami lattices on the most general microfabrication
    material, that is, silicon wafers, which has turned out to be rather challenging.
    We study how the forming of polycrystalline 2D‐fishnet‐type lattices is influenced
    by different incubation conditions and strengths of the origami–origami and origami‐surface
    interactions, with the aim to create large‐scale single‐crystalline lattices.
    The lattices are characterized by atomic force microscopy and analyzed for precision
    of formation, achievable domain size, and surface coverage of well‐formed lattices.
    Thanks to the silicon substrate, these DNA origami lattices can be further combined
    with traditional microfabrication processes to turn them, for example, into metamaterials
    with novel optical properties.</jats:p>
