However, there is little research on its application in the treatment of human choriocarcinoma.Methods and Results: In this paper, a new type of carbon-coated MoSe2 (MEC) nanoparticles was prepared by a one-step hydrothermal method. The chemical characterization including SEM, TEM, EDS, XRD, FT-IR, TGA, Roman, and XPS showed that MEC was successfully synthesized. MEC exhibited a high photothermal conversion efficiency (50.97%) and extraordinary photothermal stability under laser irradiation. The cell experiment results showed that MEC had good biocompatibility on normal cells while significant photothermal effect on human choriocarcinoma (JEG-3) cells, achieving a good anticancer effect. The level of reactive oxygen species (ROS) in JEG-3 cells was significantly increased under the combination of MEC nanoparticles and near-infrared radiation. MEC nanoparticles could induce apoptosis of JEG-3 cells in combination with near-infrared radiation. Finally, transcriptomic analysis verified that MEC combined with laser radiation could inhibit DNA replication and induce apoptosis, thus improving its therapeutic effect on human choriocarcinoma.Conclusion: MEC nanoparticles exert an excellent photothermal effect and may become an important candidate drug for the treatment of human choriocarcinoma.Keywords: MoSe2, carbon-coated, biocompatibility, human choriocarcinoma, photothermal therapy
