Nanomedicine Formulations for Respiratory Infections by Inhalation Delivery – Covid-19 and Beyond:

The surveyed literature indicates that silver NpC of diameter 3–7 nm can be highly effective in suppressing viral infections.



We estimate that these formulations can be effective for the prevention and treatment of any early-stage respiratory viral infection, including infection with SARS-CoV-2.

Virucidal effect against coronavirus SARS-CoV-2 of a silver nanocluster/silica composite sputtered coating:

…it was demonstrated that the silver nanocluster/silica composite coating deposited on facial masks possessed viricidal effect. This coating is able to completely reduce the titre of SARS-CoV-2 to zero in the conditions described here.

Potent antiviral effect of silver nanoparticles on SARS-CoV-2:

Considering the mechanism of action of AgNPs (silver nanoparticles) shown by other authors, it can be presumed that AgNPs exert their antiviral effect on SARS-CoV-2 by disrupting the disulfide bonds on the spike protein and ACE2 receptors.
