Effects of CQDs/Cu2O on the apoptosis and cell cycle distribution by flow cytometry. a Flow cytometric analysis of SKOV3 cells incubated with CQDs/Cu2O for 24Â h using an apoptosis kit with dual fluorescence of annexin V-FITC/PI. b SKOV3 were treated with CQDs/Cu2O for 24Â h and stained using PI to determine the content of DNA. The experiments were tested at least 3 times
