Story summary

Massachusetts Institute of Technology researchers led by Deblina Sarkar develop a brain implant that combines subcellular electronic devices with immune cells and may treat brain diseases including multiple sclerosis and certain brain cancers.
The devices measure 10 micrometers and are light-powered.
They travel in the bloodstream to reach the brain and cross the blood-brain barrier without invasive procedures.
In mice, the devices reached inflamed brain areas without triggering immune responses.
