Cell cycle analysis of K562 cells treated with S-GNPs after staining with PI. (a) Untreated (control) K562 cells. (b), (c), and (d) Effects of 12, 24, and 48 h, respectively, exposure of K562 cells to S-GNPs. G0/G1, G2/M, and S indicate the cell phase, and sub-G0-G1 refers to the portion of apoptotic cells.
