Fluorescent micrograph of Hoechst 33342 stained K562 cells that were treated with S-GNPs. (a) Untreated cells showing normal size and cell structure. (b) Early apoptotic cells after 24 h treatment showing chromatin condensation and membrane blebbing. (c) Blebbing and cell shrinkage after 48 h treatment. (d) Membrane blebbing, cell shrinkage, and apoptotic body formation after 72 h treatment. CC: chromatin condensation, BL: blebbing, CS: cell shrinkage, and AB: apoptotic body.
