A new gas-phase method for the one-step synthesis of metal nanoparticles supported on nanostructured metal oxides is presented by Chris Blackman and co-workers on page 1313. With no requirement for substrate pre-treatment, this provides for direct integration of the co-deposited nanomaterial with device structures and it is utilized for the fabrication of selective gas microsensor arrays based on gold and platinum decorated tungsten oxide nanorods.
