• Doctors lack reliable methods of obtaining real-time data from recovering cancer patients, with current procedures being invasive and inconsistent. MRI imaging, the most popular mechanism to keep track of a tumor, is pricey and only provides a snapshot of the state of a patient.
  • Researchers at MIT have developed a biochemical sensor to insert into cancerous tissue during the biopsy, sending a constant stream of data about specific biomarkers to an external device where doctors can monitor the patient’s status.
  • Initial experiments have shown that the sensors can accurately detect pH and oxygen concentration in tissue and are predicted to last for many years. The team is next planning to expand their monitoring capabilities for other purposes, such as collecting data from the environment from many points at once.
