Tiny devices could zap away your brain problems
MIT scientists have created Circulatronics—a new way to treat brain diseases without surgery.
Instead of cutting into the brain, doctors can inject tiny electronic devices that ride along with immune cells and find their way to problem spots.
SWEDs are small and need a microscope to see them
These "SWEDs" are so small you'd need a microscope to see them. They team up with special immune cells called monocytes, which naturally travel into the brain and target inflammation—think Alzheimer's or multiple sclerosis.
Once in place, the devices get powered by light from outside and gently stimulate neurons right where they're needed.
If it works in humans, this could make advanced treatments
Early mouse studies look promising for safety and precision.
MIT hopes to start clinical trials in the next three years, aiming to help people with brain cancer, Alzheimer's, chronic pain, and more—all without risky surgery.
If it works in humans, this could make advanced treatments much more accessible worldwide.
