flag Oregon State researchers created an iron-based nanomaterial that destroys breast cancer tumors in mice using targeted oxidative stress, with no toxicity and no recurrence.

flag Researchers at Oregon State University have developed an iron-based nanomaterial that kills cancer cells by generating two reactive oxygen species—hydroxyl radicals and singlet oxygen—specifically within tumors. flag The nanoagent targets the acidic, high-hydrogen-peroxide environment of cancer cells, causing lethal oxidative stress while sparing healthy tissue. flag In mouse models of human breast cancer, it led to complete tumor regression and long-term recurrence prevention with no systemic toxicity. flag Unlike earlier treatments, this dual-action approach shows superior effectiveness. flag The team, funded by federal health institutes, plans to test it against other cancers, including pancreatic cancer. flag Human trials are still pending.
