Antiviral Facemask That Kills Viruses

Traditional face masks, including N95s and KN95s, offer protection against illness and infection but must be disposed of once they come in contact with viruses, thus generating significant plastic waste. So now, researchers have developed a simple method that would give N95 face masks antiviral and antibacterial properties, which could allow them to be worn for longer durations.

But what if it could never get a foothold in the upper airways and stopped by just inhaling a few drops of liquid or mist beforehand?
