Abstract
Abstract A solution of amphiphilic molecules and water is atomized to form a mist of droplets which are deposited on a substrate surface to completely cover same with a coating of the solution. The amphiphilic molecules in the coating self-assemble on the surface into a continuous thin film that is less than 500 nanometers thick. The water is evaporated from the coating to leave only the film chemically bonded to the surface.
