Brookhaven Lab Center for Functional Nanomaterials (CFN) scientists Kevin Yager, Huolin Xin, Wenyan Liu (seated), Alex Tkachenko (back), and Oleg Gang with a sample of gold nanoparticle superlattices linked up by using fabricated DNA as a building material. The computer screen shows the resulting simple-FCC (left) and diamond (right) crystal lattices formed by the nanoparticles, as revealed by cryo scanning transmission electron microscopy at the CFN.
