Silver when undergone nano synthesis showed excellent performance in antibacterial applications as it inhibits the growth of Gram-Positive and Gram-negative bacteria that includes Pseudomonas Aeruginosa, Escherichia Coli, and Staphylococcus Aures . A study revealed that antimicrobial activity of many antibiotics was enhanced in the presence of silver nanoparticles (AgNPs) . AgNPs is also used as antifungal and can kill fungal strains including Candida tropicalis, Aspergillus Fumigatus, Mucor and Saccharomyces Cerevisiae . Nano silver synthesized in Hepes buffer (C8H18N2O4S) at pH 6.8 to 8.2 could inhibit HIV-1 replication and exhibit a much higher anti-HIV activity (98%) than gold nanoparticles (6-20%) .Due to its antiviral properties it is also used to inhibit Hepatitis B virus and Herpes simplex virus .
