Scaled-up non-thermal plasma-generating device Plasmatico enables effective and harmless disinfection of personal protective equipment.

ABSTRACT: The COVID-19 pandemic highlighted the urgent need to find effective methods for disinfecting items such as personal protective equipment (PPE) in case a similar situation occurs in the future. To address this problem, we selected FFP2 masks, a common PPE that cannot be easily disinfected, and developed a scaled-up non-thermal plasma (NTP)-generating device Plasmatico v1.0, which was constructed as part of a series of prototypes. It is equipped with multiple electrodes within a large exposure chamber. Using Plasmatico v1.0, we achieved complete disinfection of FFP2 masks contaminated with SARS-CoV-2, influenza A virus and human rhinovirus after 90 min, while highly resistant human adenovirus was inactivated after 120 min. In addition, Pseudomonas aeruginosa and methicillin-resistant Staphyl
