An illustration of the possible antiviral mechanisms of silver nanoparticles (AgNPs): (1) interaction of AgNPs with the viral surface; (2) interface with the cell membrane while blocking the viral attachment; (3) inhibition of cellular pathways of the virus; (4) interaction with viral genome; (5) interaction to inhibit viral genome replication; (6) inhibition of cellular factors (i.e., protein synthesis) necessary for viral replication.
