This coating makes infectious airborne droplets stick to surfaces
All it takes is a chemical commonly found in hair conditioner.
The plastic barriers that have proliferated in stores and restaurants to protect us from other people’s droplets during the pandemic—making plexiglass sales triple in the U.S.—aren’t actually proven to work. They may actually make indoor spaces more dangerous, as they interrupt the airflow that could clear the area of the droplets. But a new coating could help the surfaces be more of a deterrent by capturing the droplets in the first place.
