Princeton University Technology Overview
Motivated by the current COVID-19 pandemic, Researchers at Princeton Plasma Physics Laboratory, Princeton University, have designed a novel plasma-based in-situ device for decontaminating air flow from viruses and bacteria in real time. The use of cold, low temperature plasma to eradicate pathogens is a tested and effective technology. The Princeton device is a new steady state approach to continuously decontaminate air in ventilation systems with heating and/or air conditioning without inducing thermal or other damage.
This technology uses atmospheric plasma discharge technology for the purpose of producing cold non-equilibrium plasma(s) directed toward the targeted surface. The device can easily be made into a desirable geometry. The device is very simple in operation, constructed from inexpensive components, and powered by a simple and compact power source.
Kills bacteria and viruses
Not subject to the “shadow” problem of UV disinfection
No chemicals required
Simple to operate
Constructed from inexpensive components
Powered by a simple and compact power source
Use in residential and commercial buildings, including hospitals
Add-on to air ventilation systems with heating and/or air-conditioning with recirculation
Use as part of a portable air decontamination system including hospital rooms
Princeton is currently seeking commercial partners for the further development and commercialization of this opportunity.
