Chemical methods of sterilization- Gaseous and Liquid

17/5/2020 · NO 2 has a low boiling point (20 C) which allows a high vapor pressure at standard temperature. This property of NO 2 enables the use of the gas at standard temperature and pressure. The biocidal action of this gas involves the degradation of DNA by the nitration of phosphate backbone, which results in lethal effects on the exposed organism as it absorbs NO 2 .
