Pegylated Gold Nanoparticles Induce Apoptosis in Human Chronic Myeloid Leukemia Cells

Figure 2

K562 cells were stained with Liu’s dye for morphological examinations. Cells were treated with medium only (upper panels), 10 mM AuNPs (middle panels), after 24–72 h of treatment. The arrow indicates an apoptotic cell (lower panels). Original magnification is 1,000x for all panels.
