In-body-GPS-to-track-tumors-and-deliver-drugs

In-body GPS to track tumors and deliver drugs, a new research suggests. MIT researchers are working to make medical processes less expensive, invasive and time-consuming. On the basis of new research, they explain that an “in-body GPS” called ReMix can ease the future of medical processes.

Led by Professor Dina Katabi at the Computer Science and Artificial Intelligence Laboratory (CSAIL), MIT, the new research suggests that ReMix can track the location of ingestible implants inside the body through low-power wireless signals. They also said that this system could be used to dispense drugs to specific regions in the body.

For the findings, Katabi and colleagues implanted a little marker in animal tissues. Using a wireless device – that reflects radio signals at the patient — they track its movement. They also used a wireless device to detect the marker’s location. In addition, the group followed an existing wireless technology to detect heart rate, breathing, and movement.

According to the team, the marker reflects the signal transferred by a device outside the body, eliminating the need of a battery or other external energy sources.

“One of the roadblocks has been wireless communication to a device and its continuous localization. ReMix makes a leap in this direction by showing that the wireless component of implantable devices may no longer be the bottleneck,” says Romit Roy Choudhury, a professor of electrical engineering and computer science at the University of Illinois, who was not involved in the study.

The researchers say that the system suggests future where doctors will make use of it in therapy centers at low prices.
