Silver has been used extensively used since recorded history for variety of medical purposes due to its broad spectrum of action against variety of microorganisms. Rediscovery of this metal in the present form as silver nanoparticles (AgNPs), is being explored in wide areas of research. With the current emerging COVID-19 pandemic, as we stand on the verge of this crisis with no vaccines available and no antidote to the rapid spread of the virus, nanosilver has shown a ray of hope in the fight against COVID-19 and also in healthy future after the pandemic.
