1. A method of forming nanostructures, the method com prising:

  • patterning a nanostructure catalyst on a substrate in a plurality of non-spherical patterned elements, wherein a plurality of different nanostructure catalysts are patterned into the patterned elements;

    heating the catalyst patterned elements to form nanostructure catalyst spheres, wherein thickness and/or lateral dimension of the patterned elements controls the corresponding diameter of the catalyst spheres;

    adding nanostructure precursors to the catalyst spheres; and

    , forming nanostructures from the catalyst spheres in the presence of the nanostructure precursors.
