Scientists have developed a sheet of graphene material with minuscule holes in it that they could then place on a gold substrate. The holes allow molecules to attach to the gold exactly where the scientists want them, creating patterns that control the physical shape and electronic properties of nanoscale devices.

Metamaterials can be used to manipulate light for a range of applications, but often require complicated three-dimensional structures with features as small as a few tens of nanometers. Now, researchers have constructed a simpler, two-dimensional metasurface for state-of-the-art high-transmission light manipulation.
