A simple bottom‐up approach allows the aggregation of nanoparticles to a variety of superlattices with controlled collective properties. For example, monodisperse magnetic Fe 2 O 3 nanocrystals (blue) and PbSe semiconductor quantum dots (red) form a binary three‐dimensional AB 13 ‐type superlattice by self‐assembly (see picture).
