Aim: To develop synergistic chemo-photothermal and ferroptosis therapy nanoparticles to improve the efficacy of treatment for esophageal cancer. Materials & methods: Fe3O4@PDA-HCPT nanoparticles (NPs) were constructed and characterized. Their synergistic antitumor effects were evaluated in EC1 and EC109 esophageal cancer cells as well as in esophageal cancer-bearing mice. Results: In vitro and in vivo experiments showed that Fe3O4@PDA-HCPT NPs exhibited significant tumor inhibition and excellent diagnostic properties. The killing ability of tumor cells was significantly enhanced after irradiation. Conclusion: Synergistic application of the three therapies effectively inhibited tumor growth and exhibited potent antitumor effects, providing strong support for developing nanoparticles with synergistic antitumor effects of multiple therapies.
