Disinfection Research

Disinfection

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.
