This Magnetic Spray Turns Everyday Objects Into Walking Robots – Here’s Why It Matters

Scientists at City University of Hong Kong have created a special magnetic spray that can turn tiny objects into moving robots. These small robots, called millirobots, can walk, crawl, or roll depending on how a magnetic field controls them. The spray is made of polyvinyl alcohol, gluten, and iron particles. It sticks to objects and makes them move when a magnet is applied.

These robots are very small—about the size of an insect—and can move through the human body. They can carry medicines to a specific place inside the body, which helps avoid side effects. They can also help in medical procedures like catheter insertion.

One amazing feature is that this coating is safe for the body and can break down into powder when no longer needed. This means the robot can be removed safely or simply absorbed by the body.

The scientists tested these robots on rabbits and successfully delivered medicine to the stomach. This new technology may soon help doctors treat patients in safe and advanced ways, especially in areas of the body that are hard to reach. The future of medicine could be tiny and powerful.

The future of medicine is getting smaller, smarter, and safer!
