Morphological characters and cytotoxicity assay of AG stabilized Cu and ZnNPs, (A1 and A2) is TEM imaging of AG stabilized CuNPs showed well dispersed nanosphere particles and size ranged from 7.68 to 19.5 nm, Scale bar = 100 nm. (B1 and B2) is TEM imaging of AG stabilized ZnNPs showed spherical nanoparticles without agglomeration and size ranged from 23.4 to 39.6 nm, Scale bar = 100 nm. (C) is SRB cytotoxicity assay of AG stabilized Cu and ZnNPs at different concentrations ranged from 0.31 to 50 mg/ml
