In this study, the quantification of active oxygen species (AOS) has been investigated using silver (Ag) thin films prepared on a glass substrate as an AOS-sensing detector. On the basis of the determined values, inactivation tests of microorganisms were performed under active oxygen atmosphere in an ultraviolet (UV) lamp system. From the results, it was confirmed that the formation of silver oxide (Ag2O) derived from surface oxidation by the active oxygen influence was successfully quantified as an AOS level by inductively coupled plasma optical emission spectroscopy (ICP-OES). It was also verified that AOS exposure was an effective method for the inactivation of microorganisms.
