Microscopic bioelectronic devices, known as "circulatronics," may one day travel through the body's circulatory system and autonomously implant themselves in targeted brain regions. These implants are wirelessly powered and deliver precise electrical stimulation, potentially treating conditions such as Alzheimer’s, multiple sclerosis, and cancer.
Researchers at MIT envision a future where clinicians can place tiny electronic chips in the brain via a simple arm injection. This method could provide targeted treatment for serious brain diseases while avoiding the risks and costs associated with surgery.
In a recent study with mice, MIT scientists demonstrated that these microscopic devices can autonomously navigate to specific brain regions after injection. The implants identify their target without any human guidance and deliver focused therapy.
"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."

Author's summary: MIT researchers have developed tiny, wireless brain implants that can navigate the circulatory system and self-implant to provide precise, surgery-free electrical stimulation for treating serious brain diseases.
