Biogenic flavonoid capping converts a cytotoxic Carica papaya fraction into a selective, cross-serotype dengue entry inhibitor

It is shown that biogenic silver nanoparticle formation using a flavonoid-enriched fraction of Carica papaya inverts an unusable selectivity profile into a viable one, identifying capping chemistry, rather than silver content alone, as a determinant of the therapeutic window in phytosynthesised nanoantivirals.
