  • Surface controls nanocrystal growth, but atomic-scale hard-soft interfaces are hard to measure. Here, the authors develop electron microscopy methods to reveal the position of metal adatoms and surfactant counterions on gold nanocuboid surfaces.

  • The 3D self-assembly of nanocrystals could generate materials with unique optical and electronic properties. Barrowet al. report the DNA-mediated assembly of symmetrical 3D gold tetrahedra, pentamers and hexamers, and elucidate their plasmon modes.

  • Current techniques to determine reaction rates on the nanoscale measure ensemble averages, making it difficult to relate the catalytic activity of nanoparticles to their morphology. Researchers have now used surface plasmon spectroscopy to observe the kinetics of a redox reaction catalysed by a gold nanoparticle and also the atomic deposition of gold onto a nanocrystal.
