The one-step electrostatic complexation, reduction of aqueous chloroaurate ions and capping of the gold nanoparticles thus formed by hexadecylaniline Langmuir monolayers, is described. This process leads to the formation of highly oriented gold nanoribbons strongly bound to the Langmuir monolayer (images alongside) that may be transferred as multilayers by the Langmuir-Blodgett technique. The unusual morphology of the gold nanostructures is believed to be a consequence of highly localized reduction of the gold ions by the Langmuir monolayer.
