    Abstract: Disclosed is a device and method for contacting a biological substrate. A non-thermal plasma device delivers a non-thermal plasma discharge using a dielectric conduit, an igniter electrode and a RF electrode. The dielectric conduit fluidicly communicates a gas therethrough and an igniter electrode ionizes at least a portion of the gas. The RF electrode, disposed circumferentially proximate to the exterior of the dielectric conduit, generates non-thermal plasma from the ionized gas. The non-thermal plasma is discharged from the dielectric conduit and contacts a biological substrate. The non-thermal plasma discharge may be suitable for tissue bonding and sterilization applications.

    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 generate 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.

    Abstract: Methods and devices for treating surfaces of objects using a non-thermal plasma are disclosed herein. The non-thermal plasma is generated through the use of an apparatus configured to generate a non-thermal plasma on its surface. The apparatus is comprised of a substrate that contains one or more electrodes of different polarity. The electrodes are placed within a layer of the substrate acting as a dielectric layer. The apparatus may also have additional layers to contain the dielectric layer. When an appropriate potential, being either an alternating current or pulsed high voltage potential, is applied and removed from the one or more electrodes, the gas on at least one surface of the apparatus becomes ionized and forms a non-thermal plasma. The electrodes can be configured to be of various shapes and sizes to modify or tune the plasma.

    Abstract: Method for the non-thermal treatment of human or animal tissue with high-voltage electrical discharge plasma is disclosed. The disclosed method employs current through plasma and through tissue not for the purpose of heating the tissue, but instead to maintain the plasma proximate to the tissue being treated. Also disclosed is a method of limiting the current through plasma and through tissue to minimize tissue heating by placement of an insulator or semiconductor between an electrode and tissue resulting in generation of a high-voltage discharge similar to a dielectric barrier discharge. The disclosed non-thermal plasma treatment can be employed to promote coagulation of blood, sterilization, disinfection, re-connection of tissue, and treatment of tissue disorders without causing significant thermal tissue damage.
