Inactivation effect of the hybrid UV-LED on influenza A virus H1N1 and H6N2 subtypes. (a) Absorbance spectrum of viral RNA and emission spectrum of hybrid UV-LED. (b) Emission spectrums of the hybrid UV-LED, 258 nm UV-LED, 260 nm UV-LED, and 270 nm UV-LED at 4.8 mJ/cm2. RAE score indicates the correlation coefficient between the absorbance spectrum of viral RNA and emission spectrums of UV irradiations. Detailed conditions of the hybrid UV-LED were described in Section 3.5. (c,d) Inactivation effect of the hybrid LED on influenza A virus H1N1 and H6N2 subtypes. Viral suspensions of H1N1 (strain A/Puerto Rico/8/1934) or H6N2 (A/Duck/Hong Kong/960/1980) were irradiated by the UV-LEDs at 4.8 mJ/cm2 and infected into MDCK cells. (c) or embryonated chicken eggs. (d). Results are displayed as means ± SE (n = 5–8, n = number of independent replicates). Different letters of the alphabet indicate a statistical difference (p < 0.05) between each other. (#) indicates p < 0.05 vs. H1N1 subtype under the identical UV-LED irradiation.
