Nanoscale Building Blocks (IMAGE) DOE/Brookhaven National Laboratory Caption Controlling the self-assembly of nanoparticles into superlattices is an important approach to build functional materials. The Brookhaven team used nanosized building blocks -- cubes or octahedrons -- decorated with DNA tethers to coordinate the assembly of spherical nanoparticles coated with complementary DNA strands.
