Figure 4

Cellular uptake of magnetic nanospheres by PC12 cells. Representative (a) differential interference contrast (DIC) and corresponding (b) confocal images of PC12 cells not exposed to magnetic nanospheres. Representative (c) DIC and corresponding (d) confocal images of cells exposed to fluorescent magnetic nanospheres showing abundant internalization into cells. Scale bar in (b) = 10 μm and is valid for all images
