Electron micrographs of fibroblasts treated with Ag-np. TEM of Ag-np treated IMR-90 cells: Image shows presence of nanoparticles inside the phagosomes, near the cell membrane (A). Cell shows nanoparticles in the cytosol, nucleus and nucleoli. Arrow points to nanoparticles deposited. (B). Exocytic vesicles were observed at the cell periphery containing nanoparticles and cellular debris (C).
