Gas?phase peroxynitrite generation using dielectric barrier discharge at atmospheric pressure: A prospective sterilizer

Peroxynitrite is an important chemical in the human immune system, which has high biocidal activity and can resist invasion of pathogens. Currently, vitro generation peroxynitrite faces major technological challenges, especially for gas-phase production, requires low-pressure conditions. Here, we report method how to generate at atmospheric pressure using dielectric barrier discharge. Results show that concentration positively correlates with energy density. Moreover, Penicillium digitatum, a common fungus contaminant greatly affecting food fruit preservation, was used as microbial pathogen model confirm effects ozone-free nitrogen oxides under different discharge The germination inhibition efficiency P. digitatum highly likely attributed synergistic effect gaseous NO.
