We use a high degree of addressability of nucleic acids and their structural plasticity to direct the formation of structures from nanoscale inorganic components. We have investigated the major leading parameters determining a structure formation in such systems and explores new concepts for creating targeted nano-architectures. The principles and practical approaches developed by our group allow for assembly of well-defined three-dimensional superlattices, two-dimensional membranes and finite-sized clusters from the multiple types of the nano-components. Our recent progress on the development of by-design assembly strategies will be illustrated by nanoparticle lattices with “engineered” crystallographic symmetries, and clusters with prescribed architectures. Finally, I will discuss approaches for the dynamical control of assemblies, which allow for reconfiguration and selective triggering of system transformations. Some examples of using this assembly approach for creating optically active materials will be provided.
