Fabricating complex ordered structures, including those with hierarchical order, from nanoparticles requires understanding and controlling nanoparticle interactions for self-assembly over multiple length scales. Here we exploit building block shape and interaction anisotropy for self-assembly, and take a simulation-based approach to materials design. We exploit both forward and inverse approaches to nanoparticle assembly, incorporating elements of both positive and negative design to elucidate the necessary design elements for assembling chiral and other complex and hierarchical structures from nanocolloids. We discuss the use of "anisotropy dimensions" as an organizing framework for building block design and assembly.
