  text: Organizing inorganic nanocrystals into complex architectures is challenging
    and typically relies on preexisting templates, such as properly folded DNA or
    polypeptide chains. We found that under carefully controlled conditions, cubic
    nanocrystals of magnetite self-assemble into arrays of helical superstructures
    in a template-free manner with >99% yield. Computer simulations revealed that
    the formation of helices is determined by the interplay of van der Waals and magnetic
    dipole-dipole interactions, Zeeman coupling, and entropic forces and can be attributed
    to spontaneous formation of chiral nanocube clusters. Neighboring helices within
    their densely packed ensembles tended to adopt the same handedness in order to
    maximize packing, thus revealing a novel mechanism of symmetry breaking and chirality
    amplification.
