Antiviral activity of metallic Ag nanoparticles immobilized on textile fabrics
were investigated. The Ag nanoparticles synthesized by radiochemical process are
firmly immobilized on the surface of support textile fabrics of cotton. Small Ag
particles of about 2–4 nm were observed together with relatively
large particles of more than 10 nm. The Ag nanoparticles showed antiviral
activity against Influenza A and Feline Calicivirus. The antiviral activity
significantly depended on the concentration of the Eagle’s minimal
essential medium. It was implied that the surface passivation by inhibitory
agent lead to the deactivation of metallic Ag nanoparticles.
