First Claim
1. A method of forming at least a single conducting chain of nanoparticles between a number of contacts on a substrate comprising or including the steps of:
- a. forming contacts separated by a distance smaller than 10 microns on the substrate, b. preparing a plurality of nanoparticles, and c. randomly depositing a plurality of nanoparticles on the substrate at least in the region between the contacts until the particles form at least one chain of nanoparticles between the contacts through which conduction can occur.

Abstract
The invention relates to a method of forming a conducting nanowire between two contacts on a substrate surface wherein a plurality of nanoparticles is deposited on the substrate in the region between the contacts, and the single nanowire running substantially between the two contacts is formed by either by monitoring the conduction between the contacts and ceasing deposition at the onset of conduction, and/or modifying the substrate to achieve, or taking advantage of pre-existing topographical features which will cause the nanoparticles to form the nanowire. The resultant conducting nanowires are also claimed as well as devices incorporating such nanowires.
