Scientists Create Tumor-Tracking Implant
Scientists at Purdue University have created a device -- no larger than a needle -- that can locate tumors and detect radiation levels in chemotherapy patients. The small RFID (Radio Frequency Identification) chip is sealed hermetically in glass and powered by placing electrical coils next to the patient. When powered up, the device can send the exact dosage of radiation being received by the tumor along with the location of the tumor. This makes treatment more efficient and less dangerous to surrounding tissue and organs.
Scientists hope to enter clinical trials in 2010 with a version smaller than a grain of rice.
