Low Temperature Plasma Device for Sterilization and Antiviral Applications

Princeton Docket # 20-3699


Researchers at Princeton Plasma Physics Laboratory, Princeton University have designed a flexible dielectric-barrier discharge (DBD) device which produces a uniform, cold plasma for disinfection and sterilization. The device can easily be made into desirable geometries for a multitude of applications. Cold plasma from DBD devices has been previously shown to have beneficial biological effects and promote significant killing of bacteria and virus inactivation without inducing thermal or other damage to materials or tissues.  The effect of plasma from the device can be enhanced with various substances thereby enhancing the plasma-induced chemical reactivity. The device is very simple in operation, constructed from inexpensive components and powered by a simple and compact power source that can be battery powered.


The U.S. Department of Energy's Princeton Plasma Physics Laboratory is a Collaborative National Center for plasma and fusion science. Its primary mission is to develop the scientific understanding and the key innovations which will lead to an attractive fusion energy source. Associated missions include conducting world-class research along the broad frontier of plasma science and providing the highest quality of scientific education. 




Shurik Yatom is a Staff Research Physicist at the Princeton Plasma Physics Laboratory. He received his BS and PhD in Physics from Technion-Israel Institute of Technology in 2008/2013. His PhD thesis was focused on research of nanosecond discharges in gases at atmospheric and higher pressures and has received several prestigious awards, such as: 2014 Igor Alexeff Outstanding Student Award of the Plasma Science and Application Committee (PSAC) of the IEEE, 2013 Israel Physical Society Prize for graduate student in Experimental Physics,  IEEE Arthur H. Guenther  Pulsed Power student award 2012 and Jacobs Excellence Fellowship 2011-2012. From 2014-2016 he worked in the University of Minnesota in the department of Mechanical Engineering, where he was working on laser scattering and fluorescence diagnostics of atomic and molecular species in non-equilibrium plasmas. At PPPL Dr. Yatom is engaged in a wide variety of activities including developing and studying plasma sources for biomedical applications, plasma-assisted synthesis of nanomaterials, development and application of plasma and nanomaterial diagnostics among others.
