Fig. 10. Fluorescence imaging of AO/EB-stained HEp-2 cells (a–c) and DAPI-stained cells (d–f) exposed to pcAgNPs attributing to apoptotic cell death. Green coloration denotes viable cells (a); early apoptotic cells with green fluorescence (b); and late apoptotic cells (c); control cells with intact nuclei (d); chromatin condensation (e) associated with nuclear fragmentation (f).
