DNA‐nanoparticle superlattices are transferred to the solid state by silica encapsulation. Whereas these materials previously existed only in solution, this method allows the superlattices to remain stable in formerly inaccessible environments including in common organic solvents and at elevated temperatures. The silica‐encapsulated superlattices can be directly imaged by transmission electron microscopy (TEM) where both the lattice symmetries and interparticle spacings are preserved.
