Abstract
A method of forming a structure upon a substrate is disclosed. The method comprises: providing a substrate upon a surface of which a plurality of electrically conductive pads are disposed; depositing fluid containing a dispersion of electrically polarizable nanoparticles onto the substrate such that at least a portion of a first one of the plurality of pads is in contact with the fluid; applying an alternating electric field to the fluid using a first electrode and a second electrode, the first electrode being positioned so as to provide an effective first electrode end position from which the electric field is applied, coincident with the deposited fluid, and spaced apart from the first pad by a distance, and the second electrode being in contact with the first pad, such that a plurality of the nanoparticles are assembled to form a first elongate structure extending along at least part of the distance between the effective first electrode end position and the portion of the first pad.
