Swiss scientists just built robots so small they can swim through your bloodstream and possibly stop a stroke before it happens.
Imagine treating a stroke by guiding a microscopic robot directly to the clot no massive drug doses, no invasive tools, just precision medicine on a micro-scale.
Researchers in Switzerland have developed magnetic microrobots smaller than a grain of sand that can travel through blood vessels and deliver clot-dissolving drugs exactly where they’re needed. Using external magnetic fields, doctors can steer these tiny machines like remote-controlled rescuers, even navigating against blood flow.
Early tests in advanced vessel models and large animals show the robots gliding along vessel walls, slipping into tight spaces, and reaching areas traditional medical tools simply can’t access.
