Publication number: 20220256682Abstract: Applications of dielectric barrier discharge (DBD) based atmospheric pressure plasma jets are often limited by the relatively small area of treatment due to their 1D configuration. This system generates 2D plasma jets permitting fast treatment of larger targets. DBD evolution starts with formation of transient anode glow, and continues with development of cathode-directed streamers. The anode glow can propagate as an ionization wave along the dielectric surface through and outside of the discharge gap. Plasma propagation is not limited to 1D geometry such as tubes, and can be organized in a form of a rectangular plasma jet, or other 2D or 3D shapes. Also described are a method for generating 2D plasma jets and use of the 2D plasma jets for cancer therapy.Type: ApplicationFiled: January 3, 2022Publication date: August 11, 2022Applicants: Drexel University, Thomas Jefferson UniversityInventors: Danil V. DOBRYNIN, Alexander FRIDMAN, Abraham LIN, Vandana MILLER, Adam Snook

Patent number: 10500407Abstract: Disclosed herein are atmospheric pressure pin-to-hole pulsed spark discharge devices and methods for creating plasma. The devices include a conduit for fluidically communicating a gas, a plasma, or both, therethrough, portion of the conduit capable of being connected to a gas supply, and a second portion of the conduit capable of emitting a plasma; a positive electrode comprising a sharp tip; and a ground plate electrode. Disclosed are methods for treating a skin ulcer using non-thermal plasma include flowing a gas through a cold spark discharge zone simultaneously with the creation of a pulsed spark discharge to give rise to a non-thermal plasma emitted from a conduit, the non-thermal plasma comprising NO; and contacting a skin ulcer with said non-thermal plasma for sufficient time and intensity to give rise to treatment of the skin ulcer.Type: GrantFiled: October 25, 2016Date of Patent: December 10, 2019Assignee: Drexel UniversityInventors: Danil V. Dobrynin, Alexander Fridman, Young I. Cho, Gregory Fridman, Gennady Friedman
