UV light-emitting diodes (UV LEDs) are an emerging technology and a UV source for pathogen inactivation, however low UV-LED wavelengths are costly and have low fluence rate. Our results suggest that the sensitivity of human Coronavirus (HCoV-OC43 used as SARS-CoV-2 surrogate) was wavelength dependent with 267 nm ~ 279 nm > 286 nm > 297 nm. Other viruses showed similar results, suggesting UV LED with peak emission at ~286 nm could serve as an effective tool in the fight against human Coronaviruses.

UV-LED 对冠状病毒的消毒：波长效应

紫外线发光二极管 (UV LED) 是一项新兴技术，也是灭活病原体的紫外线源，但低 UV-LED 波长成本高昂且注量率低。我们的结果表明，人类冠状病毒（HCoV-OC43 用作 SARS-CoV-2 替代品）的敏感性与波长相关，267 nm ~ 279 nm > 286 nm > 297 nm。其他病毒也显示出类似的结果，表明峰值发射波长约为 286 nm 的 UV LED 可以作为对抗人类冠状病毒的有效工具。
