Abstract
Using atomic force anodisation lithography with a silane monolayer as a resist, patterned silicon oxide nanostructures were etched onto a silicon substrate. Condensation reactions were used to immobilise single-walled carbon nanotubes (SWCNT) onto the oxide followed by attachment of ferrocenemethanol to the nanotubes. These nanostructures are used as electrochemical electrodes to observe oxidation and reduction of ferrocene demonstrating that such controlled nanostructured electrodes are ideal candidates for molecular electronic devices, particularly molecular memory as information may be stored in discrete redox states. © The Royal Society of Chemistry 2007.
