Tumors often contain areas of oxygen-deficient tissue that frequently withstand conventional therapies. This is because the drugs applied in tumors require oxygen to be effective. An international research team has developed a novel mechanism of action that works without oxygen: polymeric incorporated nanocatalysts target the tumor tissue selectively and switch off the glutathione that the cells need to survive.
