During the epidemic, improving environmental health is very important. For mutant strains with the stronger transmission, in order to improve the protection ability, Shen Zhemin's research group specially developed this portable Air Doctor sterilization card. The sterilization card uses nano-sustained release materials to continuously release chlorine dioxide molecules to inactivate bacteria and viruses in the air. The active ingredient of chlorine dioxide can be released in a controlled manner, and it will quickly spread on the human upper body (face, head, neck, and chest), which can effectively prevent the invasion of bacteria and viruses within a radius of 50cm from the body. Currently, volunteers from SESE and some school agencies have begun to try out the card.

At present, the new coronavirus is constantly mutating, and the new mutant strains are more contagious and concealed. Experts said that wearing a mask can no longer effectively prevent the new coronavirus, and multiple methods are needed to block the spread of the virus.

In the future, the team will provide technical ideas for human beings to overcome various diseases!
