Two-dimensional cell culture in MDA-MB-231 cells. BrdU staining (a control, AgNPs-treated groups; b 24 h, c 48 h, d 72 h); TUNEL staining (e control, AgNPs-treated groups; f 24 h, g 48 h, h 72 h); Caspase-3 staining (i control, AgNPs-treated groups; j 24 h, k 48 h, l 72 h); Endo G staining (m control, AgNPs-treated groups; n 24 h, o 48 h, p 72 h). One picture as a representative for internal controls were used for all three time intervals
