Motivated by the Covid-19 pandemic and the need to find alternative methods to contain and battle it, the purpose of this innovative project is to conceive a new disinfection module equipped with a cold atmospheric plasma source. This type of plasmas have been known for their ability to generate reactive species that initiate bio-molecular reactions involved in the bacterial and viral deactivation mechanisms. The aim of this project is to investigate the disinfection capabilities of such cold plasma devices using air at atmospheric pressure. This work is a tight collaboration between the Institut of Energies of the HEIG-VD and the Institut Technologies du Vivant of the HES-SO Valais-Wallis (HES-SO University of Applied Sciences and Arts Western Switzerland), regrouping 3 plasma physicists and 4 microbiologists.
