Semiconductor Quantum Dots (CdX, X = S, Te, Se) Modify Titanium Dioxide Nanoparticles for Photodynamic Inactivation of Leukemia HL60 Cancer Cells

Figure 16

(a) Viability of HL60 cells treated with CdS-based nanocomposite B and CdS-TiO₂ without irradiation for 24 hours. Each data point represents (). indicated that there was a difference compared untreated control cells with groups of FA-CdS-TiO₂ in different concentrations, indicated that there was a difference compared untreated control cells with groups of CdS-TiO₂ in different concentrations, and ^# compared with the two groups. (b) Viability of HL60 cells treated with CdSe-TiO₂ and CdSe-based nanocomposite C (with different folic acid ratios) in different concentrations without irradiation for 24 hours. Each data point represents (). indicated that there was a difference compared with untreated control cells without irradiation, and ^# compared with the two groups. All the data shown in the figure are representative.
