 Silver nanoparticles have been shown to be effective against various types of pathogens such as bacteria, fungi, and viruses. They can also be used to prevent the spread of infectious diseases by blocking the entry of pathogenic agents into host cells. Silver nanoparticles are able to interact with the outer membranes of lipid-enveloped viruses, thereby preventing them from entering their hosts. These interactions have been observed with HIF-1, which suggests that silver nanoparticles could be used to prevent the spread of this virus.
