Abstract

COVID-19 is a highly contagious and widespread disease that has strained the global healthcare system to the hilt. Silver nanoparticles (AgNPs) are well known for their potent antimicrobial, antiviral, immunomodulatory and biosensing properties. AgNPs have been found to be potential antiviral agent that act against many deadly viruses and is presumed to be effective against COVID-19. AgNPs can generate free radicals and reactive oxygen species (ROS) leading to apoptosis mediated cell death thereby inhibiting viral infection. The shape and size of AgNPs play an important role in its biomedical applications as alterations may result in variable biological interaction and activity. Herein, we propose that AgNPs can be utilized for effective management of the ongoing COVID-19 pandemic by highlighting the current status of AgNPs in the fight against COVID-19.

Keywords: Antimicrobial; Antiviral activity; COVID-19; Cytokine storm; Silver nanoparticles.
