Determination of the Efficacy of the Cold Atmospheric Plasma with Nano Tio2 Covered in Cathode Towards Enveloped Viruses such as Covid 19 and Influenza in Room Air

In this research, Medwave air and surface disinfection system (model:Klin20)selected to investigation effect , towards aerosolised enveloped viruses in room air. Phi6Pseudomonas syringae phage, a surrogate for coronavirus influenza, was used the trials Viral suspensions of Phi6 were within ukas accreditation Campden BRI aerobiology laboratory achieve initial levels ~106PFU/m3, representing very heavily contaminated . Air samples taken at 15 minute intervals analysed determine over total test period 135 minutes. On 3 separate days, paired carried out with switched onand units witched off as control baseline virus overtime. Trials on first two days showed no reduction viral titre compared control. Further revealed that wiring loom unit had become disconnected during transport instrument therefore not functioning correctly. Results from trial level decreased rapidly an 6.12 log PFU/m3to undetectable (<1.78 PFU/m3) after 45 minutes operation, ≥4.00 logs run off. Log reductions 2.21, 3.30and observed 15, 30 respective PFU/m3countsin Keywords: Bioaerosols nano-titanium atmospheric cold plasma, covid19
