Implantable Tumor Tracker

Rather than bringing people into the lab, researchers at MIT are putting tiny labs into people via a tiny implantable capsule that can track the growth of a tumor or detect heart-deterioration or even silent heart attacks from inside the body.

The miniature lab is small enough to implant via a needle during a normal biopsy, and can remain inside the body vigilantly watching for increased tumor growth. The inside of the device is filled with nanoparticles, each sporting an antibody specially designed to bind to specific molecules like those that are produced by certain kinds of tumors or by damaged heart muscle cells.
