Particle Size Dependent Photodynamic Anticancer Activity of Hematoporphyrin-Conjugated Fe₃O₄ Particles

Figure 7

Photodynamic anticancer activities of Fe₃O₄@HPs particles. Viability of (a) prostate cancer cells (PC-3 cells) and (b) breast cancer cells (MDA-MB-231 cells). Cells were incubated with various concentrations of Fe₃O₄@HPs particles for 2 h in the dark, prior to LED irradiation for 30 min. Data are expressed as a mean ± standard deviation () and analyzed by Student’s -tests. Statistical significance was considered at . (, versus control).
