Figure 2From: Characterization of interaction of magnetic nanoparticles with breast cancer cells Electron microscopy analysis of uptake kinetics. Images from thin sections of MCF7 cells incubated with DMSA-SPION. (a) Cells incubated for 0.5 h, (b) 1 h, (c) 3 h, (d) 6 h, (e) 12 h and (f) 24 h. The inset in (f) shows the overall cell shape and morphology. Scale bars represent 1 μm for each image, 200 nm for insets in a to e, and 2 μm for the inset in f, respectively.Back to article page
