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 and reduce overall transmission. However, whether electromagnetic waves reduce SARS-CoV-2 infectivity is unclear. Here, we adapted a coplanar waveguide (CPW) to identify electromagnetic waves that could neutralize SARS-CoV-2 virus-like particles (SC2-VLPs). Treatment of SC2-VLPs, particularly at frequencies between 2.5-3.5 GHz at an electric field of 400 V/m for 2 minutes, reduced infectivity. Exposure to a frequency of 3.1 GHz decreased the binding of SC2-VLPs to antibodies directed against the Spike S1 subunit receptor binding domain (RBD). These results suggest that electromagnetic waves alter the conformation of Spike, thereby reducing viral attachment to host cell receptors. 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.
