Simple electrostatic adsorption of negatively charged gold nanoparticles onto the positively charged surface of an ionic bilayer membrane (see Figure) is demonstrated to be a viable method for the preparation of conductive gold monolayers. The membrane's regular, dense arrays of positive charges are believed to favor an almost close‐packed arrangement of gold particles, leading to electrical conductivity.
