Engineers Create Tiny Magnetic Robots for Medical Breakthroughs
Key Points: Engineers from MIT and partner universities created a new soft magnetic hydrogel to build tiny 3D robots. The new double-dip process solves the old problem of light scattering during 3D printing. Researchers built a tiny gripper that is smaller than 1 grain of sand to grab small objects. Doctors could eventually use these micro-robots to deliver medicine or take tissue biopsies inside the...
