- Scientists at Oregon State University developed an iron-based nanomaterial that targets and destroys cancer cells without harming healthy tissue.
- The nanomaterial exploits cancer's unique chemistry (acidity and high hydrogen peroxide levels) to trigger two chemical reactions, overwhelming tumors with oxidative stress.
- This approach, known as chemodynamic therapy (CDT), generates hydroxyl radicals and singlet oxygen, damaging cancer cells from within.
- Preclinical trials showed complete tumor regression in mice with no recurrence or harmful side effects.
- The team plans to test the treatment on other cancer types, including aggressive pancreatic cancer, before human trials.
- Funding was provided by the National Cancer Institute and the Eunice Kennedy Shriver National Institute of Child Health and Human Development.
