Susceptibility of enveloped and non-enveloped viruses to ultraviolet light-emitting diode (UV-LED) irradiation and implications for virus inactivation mechanisms

UV-LED treatment at 265 nm was more efficient than UV-LED treatment at 280 nm in inactivating both enveloped and non-enveloped viruses. Capsid damage is not important in virus inactivation by UV-LEDs for both enveloped and non-enveloped viruses.
