UV Inactivation and Photoreactivation of Enteropathogenic Escherichia coli.

Verification of inactivation effect of deep-ultraviolet LEDs on bacteria and viruses, and consideration of effective irradiation methods

“…The ultraviolet dose required to achieve a 99.9% sterilization or virus inactivation is available in data accumulated from papers, and applications are developed based on these data. [6][7][8][9] Figure 1 shows the spectra of a UV lamp and a 275 nm UVC-LED. The spectrum of a UV lamp spread widely from 180 to 580 nm and exhibits several small peaks other than the sterilization wavelength.…”
