Nanofibers functionalized with surfactants to Eliminate SARS-CoV-2 and other airborne pathogens

The recent SARS-CoV-2 pandemic brought to light the difficulty in controlling pathogenic bioaerosols present air. So, several studies have sought efficient and mainly sustainable technologies develop new filtering media biocidal virucidal agents. Filter composed of nanofibers stand out for having high collection efficiencies permeability. For this reason, they been widely used filters indoor environments face masks. Combined with or conventional media, addition quaternary ammonium surfactants provide action proves be an ecologically alternative. Thus, work reviews these mechanisms, their applications, perspectives novel uses engineering materials science.
