Functionalized nanoparticles in facemasks for protection of Covid 19


PDF Full Text

Abstract

The literature review of the developments of nanomaterials, application methods, their anti-viral activity confirmed the importance and highlighted the contribution of nanostructures in fighting the corona virus. In order to improve and enhanced the protection function of the facemasks against different viruses, especially last one SARS-CoV-2 (Covid 19), various nanostructures were used, fabricated and modified for that purpose. Among the others, special attention was given on carbon based (carbon nanotubes and graphene) and nano silver, TiO2, iron and cooper with antiviral and antibacterial effects. In this paper, an overview will be presented on several nanostructures used in the facemasks for preventing the spread and protection of Covid 19.
