(A) The maximum absorbance (λ max) of AgNPs were recorded as 500–550 nm in UV-Vis spectrophotometer. (B) The surface charge of AgNPs was measured to be-22.3 Mv. (C) Cell viability value of AgNPs. When L929 cells exposed to 37.5 and 75 µg/mL of AgNPs, the percentage of cells that remained alive were 55.63 and 50.22, respectively. The symbol * indicates a statistically significant difference between the 37.5 µg/mL and control negative groups (P-values < 0.05). (D) MTT cytotoxicity of AgNPs at 37.5 µg/mL and 75 µg/mL.
