Abstract
The present invention is direct to a nano-probe corona tool and uses thereof. A nano-probe corona tool is disclosed having a tip with a diameter in the nano-scale, typically around 100 nm. The nano-probe corona tool is constructed of electrically conductive material. On the other end of the tool, a pulsed voltage source outputs a pulsed voltage to generated a pulsed electrical potential at the tip. The pulsed electrical potential at the tip causes a plasma discharge corona to occur. Uses of the corona discharge include, but are not limited to, optical emission spectroscopy, in the enhancement of deposition of coatings and nanoscale welding, e.g., nanotube or nanowires to a contact pad and welding two nanowires together, and in nanoscale surgery. For example, a nano-probe comprising CNTs may be inserted into cell membranes. The resulting corona discharge may be used to destroy tumors within the cell.
