Figure 12. Cytotoxicity of Ag and Au nanoparticles on HeLa cells.

Respiratory activity of HeLa cells analyzed by MTT assay, incubated for 24 (A) and 48 h (B) with Ag and Au nanoparticles produced by using L. edodes extracellular extracts, and bright-field microscopy images of pure HeLa cells as control (C) and cells incubated for 24 h with nanoparticles in varying concentrations (D–H). Bar markers –100 µm.
