Microscopic Studies of Various Sizes of Gold Nanoparticles and Their Cellular Localizations
Figure 7
AFM imaging of 25 nm gold nanoparticles into HEp-2 cells after 1 (a), 2 (b), 4 (c), 12 (d), and 24 hr (e) incubations. All images are 45 by 45 microns, except for images (b) and (e) which are 40 by 40 microns.
