They observed a superlattice measuring 20 microns, with a distance between lines of nanoparticles — or lattice constant — of 8.8 nanometers. He said the 20-micron superlattice domain is the largest ever documented, and this new technique could lead to even larger superlattices with even tinier features.
Journal of Materials Chemistry - A very large two-dimensional superlattice domain of monodisperse gold nanoparticles by self-assembly
We report a very large 2D superlattice domain of hexagonal close-packed monodisperse gold nanoparticles, which is longer than 20 μm and of 8.8 nm superlattice constant in a millimetre-scale monolayer film, fabricated by simple self-assembly of drying water and toluene droplets with 2D nanoparticles at the air–liquid interfaces.
