Syndrome coronavirus 2 (SARS-CoV-2) infectious virions are viable on various surfaces (e.g., plastic, metals, and cardboard) for several hours. This presents a transmission cycle for human infection that can be broken by developing new inactivation approaches. We employed an efficient cold atmospheric plasma (CAP) with argon feed gas to inactivate SARS-CoV-2 on various surfaces including plastic, metal, cardboard, basketball composite leather, football leather, and baseball leather. These results demonstrate the great potential of CAP as a safe and effective means to prevent virus transmission and infections for a wide range of surfaces that experience frequent human contact. Since this is the first-ever demonstration of cold plasma inactivation of SARS-CoV-2, it is a significant milestone in the prevention and treatment of coronavirus disease 2019 (COVID-19) and presents a new opportunity for the scientific, engineering, and medical communities.

用于灭活 SARS-CoV-2 的冷大气等离子体


综合症冠状病毒 2 (SARS-CoV-2) 感染性病毒颗粒可在各种表面（例如塑料、金属和纸板）上存活数小时。这提出了人类感染的传播周期，可以通过开发新的灭活方法来打破。我们采用高效的冷大气等离子体 (CAP) 和氩气进料气体来灭活各种表面上的 SARS-CoV-2，包括塑料、金属、纸板、篮球复合皮革、足球皮革和棒球皮革。这些结果证明了 CAP 作为一种安全有效的手段来防止人类频繁接触的各种表面的病毒传播和感染的巨大潜力。由于这是首次演示冷血浆灭活 SARS-CoV-2，因此它是预防和治疗 2019 年冠状病毒病 (COVID-19) 的一个重要里程碑，并为科学、工程和应用领域提供了新的机遇。医疗社区。
