Design rules allow the synthesis of nanoparticle-DNA superlattices in nine different lattices. A current limitation in nanoparticle superlattice engineering is that the identities of the particles being assembled often determine the structures that can be synthesized. Therefore, specific crystallographic symmetries or lattice parameters can only be achieved using specific nanoparticles as building blocks (and vice versa). We present six design rules that can be used to deliberately prepare nine distinct colloidal crystal structures, with control over lattice parameters on the 25- to 150-nanometer length scale. These design rules outline a strategy to independently adjust each of the relevant crystallographic parameters, including particle size (5 to 60 nanometers), periodicity, and interparticle distance. As such, this work represents an advance in synthesizing tailorable macroscale architectures comprising nanoscale materials in a predictable fashion.

Programmable materials and the nature of the DNA bond (2015, positive): “This hypothesiswas tested and confirmed in numerous subsequent investigations and now forms the basis for a series of design rules that guide and explain the formation of dozens of different superlattice symmetries (3, 74, 75).”
