Apoptosis results for cells labeled with different concentrations of silica‐coated MZF nanoparticles. Cells were incubated for 48 h and then labeled with FITC‐dUTP; the proportion of FITC‐positive apoptotic events within nucleated singlet cells was determined. The negative control represents unlabeled stained cells, while the positive cells are apoptosis‐induced cells included in the kit.
