Flow cytometry analyses of groups A, B, C, and D. Group A cells are the blank control; group B cells were treated with 5 mg/L nanoscale Photosan for 2 h at 5 J/cm2; group C, cells received 5 mg/L conventional Photosan for 2 h at 5 J/cm2; group D cells were treated with 10 mg/L conventional Photosan for 4 h at 10 J/cm2. Lower left quadrants represent normal cells; lower right quadrants are early apoptotic cells; upper right quadrants represent late, dead apoptotic cells; upper left quadrants are mechanically damaged cells. The apoptotic rate was defined as100* (sum of early apoptotic and late apoptotic cells)/total number of cells.
