Claim:
1. A method for controlling dimensions of nanowires, comprising: placing a light mask on a layer of polymer resin; using optical lithography with the light mask, photo-lithographically forming a trench in the layer of a polymer resin, the trench having sidewalls and a bottom with a width less than one micrometer and a length corresponding to a desired length of a nanowire to be formed, said polymer resin being deposited over an electrically conductive substrate; exposing a surface of the conductive substrate at the bottom and between the sidewalls of the trench; depositing a metallic nanowire material by electroplating within said trench over the exposed surface of the conductive substrate at the bottom of the trench to form a metallic nanowire longitudinally along said substrate, a length of said nanowire corresponding to a length of said trench; and removing said nanowire from said substrate with a removal mechanism.
