Charge control as a tool for assembly : Dense layers of individual, charged nanocrystals are formed at the aqueous/organic interface upon a slight reduction of the surface charge. The layers are remarkably robust, they creep up the glass (see picture). This method should be widely applicable to a broad range of charged colloids and will lead to the production of new materials.
