Abstract:
The transmission of viral infections via aerosol has become a serious threat to public health. This has produced an ever-increasing demand for effective forms of viral inactivation technology/processes. Plasma technology is rising in popularity and gaining interest for viral disinfection use. Due to its highly effectively disinfection and flexible operation, non-thermal plasma (NTP) is a promising technology in decontaminating bacteria or virus from air or surfaces. This review discusses the fundamentals of non-thermal plasma and the disinfection mechanisms of the biocidal agents produced in plasma, including ultraviolet (UV) photons, reactive oxygen species, and reactive nitrogen species. Perspectives on the role of catalysts and its potential applications in cold plasma disinfection are discussed.

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
Methods of Sterilization I: Physical Methods
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...
