Two-dimensional thin films are often fabricated using bottom-up solution-based techniques, such as electrochemical deposition and atomic layer deposition. Now researchers have reported a top-down, solid-state method based on the age-old Egyptian craft of goldbeating that they say is generalizable to various metallic, polymeric, or ceramic nanoparticles.
