New iron nanomaterial wipes out cancer cells without harming healthy tissue

Scientists at Oregon State University have engineered a powerful new nanomaterial that zeroes in on cancer cells and destroys them from the inside out. Designed to exploit cancer’s unique chemistry—its acidity and high hydrogen peroxide levels—the tiny iron-based structure sparks not one but two intense chemical reactions, flooding tumors with cell-damaging oxygen molecules. This dual attack overwhelms cancer cells with oxidative stress while sparing healthy tissue.
