Nanodots are produced over large areas with controlled size and density in a new single-step, low-cost process. This process is based on surfactant-made multilamellar vesicles that serve as nanovectors. Copper ions are incorporated inside vesicles by chemical complexation. Vesicles are attracted under a DC electric field towards an electrode, where they are reduced to produce the metal nanodots shown in the figure.
