Abstract

Due to the current pandemic situation caused by SARS-CoV-2 the need of effective precautionary methods is increasing. Besides the transmission of this virus by aerosols induced to air, it is assumed that the transmission route of SARS-CoV-2 is mainly by contaminated surfaces. It has been demonstrated that viruses can contaminate dry surfaces and can be further transmitted to the host even after extended time. The amount of disinfection and hygiene systems has increased drastically over the recent year. Although, the conventional disinfection method via spraying and wiping is labour intensive and efficacy is dependent on the application. Aim of this study was to improve conventional disinfection methods. This new disinfection system based on hydrogen peroxide and silver nanoparticles displays a quick and effective alternative. The composition which was proposed in this study shows unique features in terms of application, health risk and effectivity. The novel application by vaporization helps to disinfect the environment and even the air to reduce virus spreading. New disinfection formulation shows efficacy on the surface proteins and genetic information of the virus. Integration of the effective disinfection method shown in this study in the current precaution measurements will help to reduce the spread of SARS-CoV-2.
