Abstract
Photothermal therapy is a promising approach for cancer treatment. In our study, we investigate the photothermal effect of different concentrations of the Ag@Fe3O4 nanoparticles on apoptosis and proliferation in the human epithelial ovarian cancer cells SKOV3. Ovarian cancer cells SKOV3 were treated with the Ag@Fe3O4 nanoparticles under an 808 nm near-infrared (NIR) laser irradiation at different concentrations. The cell proliferation was measured by the cell counting kit-8 (CCK-8) assay. The results show that the Ag@Fe3O4 nanoparticles with NIR laser irradiation could markedly inhibit the proliferation of the ovarian cancer cells SKOV3 independent of a concentration-time manner. Meanwhile, the cell morphology was also seriously damaged under the treatment of high-concentration nanoparticles. However, Ag@Fe3O4 nanoparticles have almost no obvious effect on the growth of SKOV3 cells without NIR laser illumination treatment. Therefore, it is reasonable to believe that the Ag@Fe3O4 nanoparticles have promising applications in photothermal treatment of cancer cells.
