flag MIT scientists created injectable chips that target the brain, treat disorders like Parkinson’s, and avoid surgery.

flag MIT researchers have developed injectable, microscopic electronic chips that can travel through the bloodstream, self-implant in targeted brain areas, and deliver wireless electrical stimulation to treat disorders like Parkinson’s, epilepsy, and depression. flag Coated with living cells, the chips evade the immune system and cross the blood-brain barrier without surgery. flag In mouse studies, they reduced brain inflammation and integrated with neural tissue, offering a non-invasive alternative to traditional brain implants. flag The technology, published in Nature Biotechnology on November 5, 2025, could one day treat a range of neurological and mental health conditions and may be adapted for other body parts.
