SEM micrographs representing the morphology of the mouse fibroblasts (upper) and human osteosarcoma (lower) cells without (control) or upon contact with AuNPs. The gold nanoparticles were deposited on the cell surface (yellow arrows). Scale bars 6 µm. Operating parameters: det SE, HV = 20–30 kV, Mag = 10–12 kx, Specimen Current = 30–100 pA
