The one‐step synthesis of a free‐standing, robust gold nanoparticle membrane (see Figure) via the spontaneous reduction of aqueous chloroaurate ions by oxyethylene‐bearing diamine molecules in chloroform at the liquid–liquid interface is described. Such simply assembled membranes may have important applications in separation methodologies and as surfaces for enzyme, DNA, and cell immobilization.
