Sensor could help doctors select effective cancer therapy

Hydrogen peroxide-sensing molecule reveals whether chemotherapy drugs are having their intended effects.

Anne Trafton | MIT News Office

MIT chemical engineers have developed a new sensor that lets them see inside cancer cells and determine whether the cells are responding to a particular type of chemotherapy drug.

The sensors, which detect hydrogen peroxide inside human cells, could help researchers identify new cancer drugs that boost levels of hydrogen peroxide, which induces programmed cell death. The sensors could also be adapted to screen individual patients’ tumors to predict whether such drugs would be effective against them.
