Pegylated Gold Nanoparticles Induce Apoptosis in Human Chronic Myeloid Leukemia Cells
Figure 3
Morphological appearance of gold nanoparticles (AuNPs) with their surface modified by polyethylene glycol (PEG-AuNPs) imaged by transmission electronic microscopy. K562 cells were incubated with (a) medium only, 10 mM of PEG-AuNPs, for (b) 24 h, (c) 48 h, and (d) 72 h. Original magnification is 4,000x for all panels.
