Stents and Bypass Surgery No Longer Needed – A Breakthrough by Scientists

Scientists at Drexel University in the United States have made an exciting new discovery that could completely change how heart diseases are treated. They have developed tiny machines called microrobots or nanobots that may replace traditional procedures like stent placement or bypass surgery.

These microscopic robots can move through the bloodstream and reach areas where fat and cholesterol have built up inside the arteries. Without needing any surgery, these nanobots can break down and clear out blockages, helping blood flow return to normal.

What Are These Nanobots and How Do They Work?

According to Smithsonian Magazine, the microrobots are made from iron oxide particles and are designed to join together into a spiral chain shape. This design helps them move easily through blood vessels. Scientists control them using an external magnetic field, guiding them directly to blocked areas in the arteries.

Once they arrive, the nanobots soften and dissolve the fatty deposits, clearing the blockage. These robots are safe for the human body and naturally break down and disappear after finishing their task.

Researchers say that this new method is safer and more successful than current treatments like stents or bypass surgery. Since it doesn’t require surgery, it also means less pain and faster recovery for patients. Plus, there’s a much lower risk of complications.

This project is being developed with the help of 11 research institutions from around the globe, including Switzerland, South Korea, and the USA. Drexel University is representing the United States in this global effort.

The team plans to start animal testing by the end of this year, which will be a big step toward beginning human trials in the future. Scientists believe that these nanobots may also be useful for treating other serious illnesses like cancer. This invention could open a new chapter in medical science, giving hope to millions of people.

If this technology is successful, it could save people from costly and painful surgeries in the coming years, making heart treatment simpler, safer, and more affordable.
