Methods of forming a dispersion of nanostructures, a distribution of carbon nanotubes, and an array of nanostructure devices, such as sensors or transistors, are described. The methods involve providing a substrate, applying growth promoter to at least a portion of the substrate, exposing the substrate and the growth promoter to a plasma, and then forming a dispersion of nanostructures from the growth promoter. The plasma disperses the growth promoter as distinct, isolated growth promoter nanoparticles between about 1 nm and 50 nm in size over the substrate. An array of nanostructure devices includes a dispersion of nanostructures and an array of electrodes in contact with the nanostructures. Nanostructures are removed from some areas, leaving regions containing nanostructures to provide electrical communication between two or more electrodes, thus forming an array of nanostructure devices. |
