We demonstrate the preparation of selective nanostructured vanadium oxide chemical sensors using chemical vapor deposition precursor chemistry to control film microstructure. The origins of the response selectivity may be traced back to the nature of the bonding in the chemical precursors used for preparing the sensing films. We provide examples of sensing response to 1-propanol and nitrogen dioxide, each a reaction product in the formation of one of the materials.
