“Researchers at the University of Alberta have developed a virus-killing salt coating that’s designed to improve the effectiveness of the common surgical masks often used to prevent the spread of pathogens like influenza or the new coronavirus.
The sodium chloride coating applied to the surface of the surgical mask is designed to kill any virus particles which can otherwise survive for up to a week — a risk researchers say the average person isn’t aware of.
The salt coating, which has been under development since 2015, essentially works to kill any particles of the virus it comes into contact with.
‘When virus-carrying water droplets sit on the surface, the salt dissolves and water begins to evaporate,’ he explained. ‘During the evaporation process the salt crystals begins to grow and a very sharp edge of the crystal basically destroys the virus.'”
