We have shown that self-assembled DNA nanotubes of micrometric length condense into superstructures upon addition of sufficient amounts of multivalent cations, such as Mg 2+ , the triamine spermidine and the tetraamine spermine. We demonstrated the strong analogy with the phenomenology of DNA condensation, through i) the crucial role of counter-ion valency (the higher the valency, the lower the charge ratio indeed to induce a transition) and ii) the formation of rings the size of the order of the nanotube persistence length resembling the toroids formed by DNA condensation and with similar internal DNA organization. In term of the structures obtained, the system also recapitulated some of the known features obtained with other semi-flexible or rigid polyelectrolytes such as actin filaments and microtubules, with the formation of networks and bundles, thus reinforcing knowledge of the electrostatic assembly of polyelectrolytes as well as opening perspectives for building cytoskeletoninspired materials. Mainly driven by electrostatics, the assembly principles explored here provide a ubiquitous basis for the formation of superstructures independent of their detailed chemistry. It is therefore not only a means of building higher-order superstructures combining nanoscale DNA programmability with extended dimensions, but also a strategy for organizing bricks other than DNA.
