DNA strands anchored to the surface of nanoparticles allow researchers to assemble the particles into three-dimensional crystalline lattices. Such control allows researchers to make new materials with desirable properties. In two recent studies, independent teams adapted this approach to gain even more control over assembly.

One team, led by Chad A. Mirkin of Northwestern University, designed “transmutable” DNA-coated nanoparticles that can switch from one lattice structure to another on demand in response . . .
