Chinese scientists developed a worm-shaped, magnetically controlled implant that monitors neural activity with high precision and long-term safety in mice.
Chinese scientists have created NeuroWorm, a flexible, earthworm-inspired microfiber that moves through body tissues using magnetic control to monitor neural signals and tissue changes.
About 200 micrometers wide—thinner than two human hairs—it contains 60 nano-scale sensors, 15 times more than traditional devices, enabling precise, long-term, multi-point recordings.
Tested in mice, the implant remained biocompatible for up to 13 months without adverse reactions.
Unlike fixed implants, it can navigate the brain or muscles without repeated surgeries, potentially revolutionizing brain-machine interfaces and treatments for neurological disorders like Parkinson’s.
The study, published in Nature, represents a shift toward mobile, intelligent neural systems.
Led by Yan Wei of Donghua University and Liu Zhiyuan of the Chinese Academy of Sciences, the team plans to collaborate on advancing clinical use.
Científicos chinos desarrollaron un implante en forma de gusano, controlado magnéticamente que monitorea la actividad neuronal con alta precisión y seguridad a largo plazo en ratones.
