MIT Researchers Developing Injectable Chip for Brain Disorders
Circulatronics devices cross the blood-brain barrier without surgery and provide precise brain stimulation to treat diseases, with clinical trials planned within three years.
- On November 10, 2025, Massachusetts Institute of Technology researchers unveiled microscopic wireless circulatronics that travel through the bloodstream and self-implant in targeted brain regions, powered wirelessly by external electromagnetic transmitters.
- Researchers fused electronics with monocytes to cross the intact blood-brain barrier without opening it, using a chemical reaction to bond devices and freeing them from silicon wafers after years of work.
- The devices measure about one‑billionth the length of a grain of rice and biocompatibility tests showed the implants integrate among neurons without harming cognition or motion.
- Cahira Technologies aims to advance trials within three years, hoping the platform could treat glioblastoma and diffuse intrinsic pontine glioma while reducing surgery risks.
- As a platform, the technology could integrate additional nanoelectronic circuits for sensing and feedback, and extend future applications beyond the brain to other body parts.

Therapeutic brain implants could defy the need for surgery
What if clinicians could place tiny electronic chips in the brain that electrically stimulate a precise target, through a simple injection in the arm? This may someday help treat deadly or debilitating brain diseases, while eliminating surgery-related risks and costs. MIT researchers have taken a major step toward making this scenario a reality. They developed microscopic, wireless bioelectronics that could travel through the body’s circulatory …
Imagine treating devastating brain diseases not through open skull surgery, but through a simple injection into the arm. This is the promise of a spectacular breakthrough from MIT laboratories.
