Abstract:
A method of producing nano-tweezers comprising at least two carbon nanotube tips, comprising the steps of:providing a tip assembly; applying at least two independent electrodes to the tip assembly; and applying at least one carbon nanotube tip to each of the electrodes to produce a nanotweezer, wherein the spacing between respective end portions of the carbon nanotube tips changes in response to a voltage applied between the at least two electrodes; wherein applying the at least one carbon nanotube tip comprises the steps of: applying metallic catalytic material to at least one electrode; and inserting said at least one electrode into a CVD reactor; and exposing said at least one electrode to a gaseous atmosphere comprising a carbon containing gas, thereby producing at least one electrode bearing a carbon nanotube tip.
