US scientists develop coating to capture airborne droplets
Washington (AFP) - US scientists said Wednesday they had developed a sticky wall coating that repurposes ingredients used in hair conditioners to trap aerosolized droplets, and hope it will become another tool in the fight against Covid and other airborne diseases. The substance can be applied to surfaces such as plexiglass dividers to capture respiratory droplets, rather than allowing them to bounce off and remain in circulation. "Droplets collide with indoor surfaces all the time," said Northwestern University engineering professor Jiaxing Huang, senior author of a paper on the subject that ...
