  - "<jats:title>Abstract</jats:title>\r\n<jats:p>The surface-assisted hierarchical
    self-assembly of DNA origami lattices represents a versatile and straightforward
    method for the organization of functional nanoscale objects such as proteins and
    nanoparticles. Here, we demonstrate that controlling the binding and exchange
    of different monovalent and divalent cation species at the DNA-mica interface
    enables the self-assembly of highly ordered DNA origami lattices on mica surfaces.
    The development of lattice quality and order is quantified by a detailed topological
    analysis of high-speed atomic force microscopy (HS-AFM) images. We find that lattice
    formation and quality strongly depend on the monovalent cation species. Na<jats:sup>+</jats:sup>
    is more effective than Li<jats:sup>+</jats:sup> and K<jats:sup>+</jats:sup> in
    facilitating the assembly of high-quality DNA origami lattices, because it is
    replacing the divalent cations at their binding sites in the DNA backbone more
    efficiently. With regard to divalent cations, Ca<jats:sup>2+</jats:sup> can be
    displaced more easily from the backbone phosphates than Mg<jats:sup>2+</jats:sup>
    and is thus superior in guiding lattice assembly. By independently adjusting incubation
    time, DNA origami concentration, and cation species, we thus obtain a highly ordered
    DNA origami lattice with an unprecedented normalized correlation length of 8.2.
    Beyond the correlation length, we use computer vision algorithms to compute the
    time course of different topological observables that, overall, demonstrate that
    replacing MgCl<jats:sub>2</jats:sub> by CaCl<jats:sub>2</jats:sub> enables the
    synthesis of DNA origami lattices with drastically increased lattice order.</jats:p>@eng"
