Abstract

Infection and transmission of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) continues to pose a global public health concern. Using electromagnetic waves represents an alternative strategy to inactivate pathogenic viruses such as SARS-CoV-2. However, whether electromagnetic waves reduce SARS-CoV-2 infectivity is unclear. Here, we adapted a coplanar waveguide (CPW) to identify frequencies that could potentially neutralize SARS-CoV-2 virus-like particles (SC2-VLPs). Treatment of SC2-VLPs at frequencies between 2.5 and 3.5 GHz and an electric field of 413 V/m reduced infectivity. Exposure of SC2-VLPs to a frequency of 3.1 GHz -and to a lesser extent, 5.9 GHz- reduced their binding to antibodies targeting the SARS-CoV-2 Spike S1 receptor-binding domain (RBD) but did not alter the total levels of Spike, Nucleocapsid, Envelope, or Membrane proteins in virus particles. These results suggest that electromagnetic waves alter the conformation of Spike, thereby reducing viral attachment and entry. Overall, this data provides proof-of-concept in using electromagnetic waves for sanitation and prevention efforts to curb the transmission of SARS-CoV-2 and potentially other pathogenic enveloped viruses.

摘要

严重急性呼吸综合征冠状病毒2(SARS-CoV-2)的感染和传播仍然是一个全球公共卫生问题。利用电磁波是一种灭活诸如SARS-CoV-2等致病性病毒的替代策略。然而,电磁波是否会降低SARS-CoV-2的感染性尚不清楚。在此,我们采用共面波导(CPW)来确定可能中和SARS-CoV-2病毒样颗粒(SC2-VLPs)的频率。在2.5至3.5GHz频率和413V/m的电场下处理SC2-VLPs可降低其感染性。将SC2-VLPs暴露于3.1GHz频率下——在较小程度上,还有5.9GHz——会降低它们与靶向SARS-CoV-2刺突S1受体结合域(RBD)的抗体的结合,但不会改变病毒颗粒中刺突、核衣壳、包膜或膜蛋白的总量。这些结果表明,电磁波会改变刺突的构象,从而减少病毒的附着和进入。总体而言,这些数据为利用电磁波进行卫生清洁和预防工作以遏制SARS-CoV-2以及潜在的其他致病性包膜病毒的传播提供了概念验证。
