Soft graphene-based probe monitors brain and gut chemistry

Scientists from Michigan State University and Stanford University have invented the “NeuroString” — a graphene-based implantable probe that enables researchers to study the chemistry of brain and gut health.

“The mainstream way people are trying to understand the brain is to read and record electric signals,” said Jinxing Li, the paper’s first author and an assistant professor in MSU’s College of Engineering. “But chemical signals play just as significant a role in brain communication, and they are also directly related to diseases. My lab at MSU focuses on developing cutting-edge neuroprobes and microrobotics.”
