COVID-19: Scientists develop wall coating that can capture aerosols and droplets from air - WION

COVID-19 is primarily transmitted through respiratory fluids, including large droplets and fine aerosols, when an infected person speaks, sneezes or breathes.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 was published Wednesday in the journal Chem.COVID-19 is primarily transmitted through respiratory fluids, including large droplets and fine aerosols, when an infected person speaks, sneezes or breathes.A coated plexiglass barrier captured nearly all aerosolized microdroplets, and 80 percent of large droplets, compared to a barrier that was uncoated.Since it can be applied to a variety of surfaces, including concrete, metal, and fabric, Huang said it could be used on low-touch areas such as walls or curtains to turn those into "functional devices" that would help capture aerosolized particles
