A method for depositing a coating of a nanostructure material onto a substrate includes: (1) forming a solution or suspension of containing the nanostructure material; (2) selectively adding 'chargers' to the solution; (3) immersing electrodes in the solution, the substrate upon which the nanostructure material is to be deposited acting as one of the electrodes; (4) applying a direct and/or alternating current electrical field between the two electrodes for a certain period of time thereby causing the nanostructure materials in the solution to migrate toward and attach themselves to the substrate electrode; and (5) subsequent optional processing of the coated substrate.

Deposition method for nanostructure materials

A method for attaching nanostructure-containing material onto a sharp tip of an object includes forming a suspension of pre-formed nanostructure-containing material in a liquid medium. An electrode is immersed in the suspension. The sharp tip of the object is arranged to be in contact with the suspension. A voltage is applied to the immersed electrode and to the sharp tip. The nanostructure-containing material attaches to the sharp tip of the object.
