Morphology of green synthesized Ag NPs and their antiviral activity on different viral strains.
| Phytoconstituents | Size by TEM/SEM with morphology | Viral strain | Antiviral activity (IC50/MNTD/TCID50/ml) | Reference |
| Alkaloids, terpenoids, flavonoids, glycosides, phenols, and tannins | TEM 27.89 nm Spherical in shape | | IC50 | [127] | HSV-1 | 36.36 μg/ml | HAV-10 | 11.71 μg/ml | CoxB4 | 12.24 μg/ml |
| Polyols, flavonoids, polyphenols, and terpenoids | SEM average size 70–95 nm | Chikungunya | MNTD: 31.25 μg/mL | [4] |
| Polyphenols | SEM average size 100 nm Spherical in shape | Dengue (DEN-2) | TCID50/ml | [128] | Viral titer 3.2 log10 at 20 μl/ml Ag NPs |
| Lignocellulose | TEM 3–10 nm Narrow in shape | Chikungunya | IC50: 11.73 μg/ml | [129] |
| — | SEM average size 42 nm Spherical in shape | H7N3 influenza virus | IC50: 101 μg/ml (during viral infection) and 125 μg/ml (after viral infection) | [130] |
