UV inactivation of microorganisms

Traditional ultraviolet disinfection depended on spectral lines from mercury vapor lamps within the absorbance range of DNA. Research at Phoseon examines the efficacy of high-irradiance, narrow-band LED lamps at multiple wavelengths matched to specific bonds in DNA, RNA, and proteins within target microorganisms. Higher-than-dose-predicted efficacy may be possible with high irradiance and light targeted at specific, critical molecular bonds in the microorganism.

Microorganism inactivation with experimental dose response and projected time to log 6 reduction at 275 nm and 4W/cm² irradiance.
