Cheap and effective, water filtration membranes have been around for years but have always been vulnerable to clogging from organic and inorganic materials
Researchers wanted to develop a membrane that more efficiently filters particles the size of SARS-CoV-2 and could be replaced on an N95 mask after every use
A recent study was initially inspired by the way our cells transport water throughout the body and began as an attempt to develop artificial channels for transporting water across membranes
