Nanostructures constructed from metal and semiconductor nanocrystals conjugated to and organized by DNA are an emerging class of materials with collective optical properties. We created discrete pyramids of DNA with gold nanocrystals at the tips. By taking small-angle X-ray scattering measurments fr...
