A new cloth mask can kill 99.9% of bacteria and viruses if sun is exposed for one hour – study


Los Angeles: Researchers have developed a reusable mask of cotton cloth that can kill 99.99 percent of bacteria and viruses if kept in sunlight for one hour.

Masks made from different types of clothes prevent droplets when coughing and sneezing, which can help reduce the spread of other diseases including Kovid-19.

According to a study published in the journal ACS Applied Materials and Interfaces, bacteria and viruses on masks can be contagious.

Researchers at the University of California in the US have developed a new cotton fabric that emits ‘reactive oxygen spikes’ (ROS) when exposed to sunlight that kills microorganisms on the fabric and is washable, reusable, and It is safe to apply. He said that a person can make bacteria free by placing his mask in the sunlight during lunch.

The team found that a cloth made from Bengal dye as a photosensitizer every day kills 99.99 percent of the bacteria applied to it in an hour when exposed to sunlight and activates 99.99 percent of T7 ‘bacteriophage’ within 30 minutes. T7 bacteriophage is believed to be more resistant to ROS than some corona viruses.
