An experimental rice-sized implant monitors how drugs affect tumors

Researchers at Brigham and Women's Hospital in Boston have developed an implant, notably as small as a grain of rice, that can test the effects of drugs on a patient's brain tumor in real-time during surgery. Currently, monitoring the effects of drugs on a brain cancer patient during surgery is limited to intraoperative brain imaging and tissue sampling after a drug has been administered . The technique known as microdialysis currently stands as one of the more minimally invasive sampling option...
