Anisotropic nanoparticles have their distinct properties which can be achieved by manipulating their shape and/or size. Nevertheless, the assembly of anisotropic nanostructures remains a challenge, compared to the assembly of traditional spherical nanoparticles. Using various synchrotron X-ray scattering techniques, a research group from Ames Laboratory revealed the assembly of PEG-grafted nanotriangles and nano-octahedra at the air/liquid interfaces and in the bulk.
