South Korean researchers have developed a microrobot capable of delivering neural network treatments to a target point of a mouse brain’s hippocampus. The Korea Brain Research Institute led the research team, comprising academics from the Daegu Gyeongbuk Institute of Science and Technology’s Department of Robotics and Mechatronics Engineering. The microrobot was loaded with magnetic nanoparticles, so it could move like a 3D “sphere” in response to magnetic fields. It was shown to stimulate nerve cells in the mouse brain without inhibiting their growth. The technology, tested in an in vitro environment, could offer a precise, minimally invasive way to deliver cell therapy products and could have implications for medical research in fields including regenerative medicine. The technique has been published online in Advanced Materials, a top-rated materials science journal.
