Metal-free magnetic sensor can be safely implanted for wireless monitoring

Researchers in the U.S. and China have created a biocompatible, metal-free magnet that can be safely implanted and generate signals from deep inside the body. Led by Wubin Bai at the University of North Carolina, the team revealed how magnetism can emerge from the rearrangement of atoms in heated carbon nitride, which strengthens the coupling between unpaired electrons.
