Iron nanomaterial wipes out tumors in mice while sparing healthy tissue
Mar 3rd 2026
Oregon State University researchers report an iron nanomaterial that triggers two reactive oxygen species inside tumor cells, achieving complete tumor regression in mice without damaging surrounding healthy tissue.
- The iron-based metal-organic framework generates both hydroxyl radicals and singlet oxygen inside cancer cells.
- The material exploits tumor acidity and high hydrogen peroxide levels to trigger those reactions.
- In vitro tests showed strong toxicity to multiple cancer cell lines with minimal harm to noncancerous cells.
- Systemic dosing in mice with human breast tumors produced complete tumor regression with no recurrence and no systemic toxicity.
- Researchers from Oregon State University published the work in Advanced Functional Materials and plan tests in other cancers before human trials.
