Revolutionary Micro-Robots to Replace Heart Surgery, Developed by Drexel University Scientists
Philadelphia:Scientists at **Drexel University**, USA, have made a groundbreaking invention that could replace traditional heart treatments such as stents or bypass surgeries. These tiny microscopic machines, known as **micro-robots** or **nano-bots**, travel through human blood vessels to reach areas where fat and cholesterol have accumulated. These machines have the ability to **break down harmful particles** and **clear arteries** without the need for any surgery.
According to **Smithsonian Magazine**, these micro-robots are made of **iron oxide particles**, which link together to form a spiral chain-like structure. They are controlled by an **external magnetic field**, allowing them to move through the bloodstream and reach blocked or clogged arteries with ease. Their main function is to **soften and dissolve accumulated fat**, effectively restoring the health of the arteries.
### **Key Features of the Invention:**
* **Biologically Safe**: These nano-machines are safe for the human body and **dissolve after completing their work**.
* **Higher Success Rates**: Researchers claim that this method has a **much higher success rate** compared to traditional treatments, with significantly fewer risks.
This project is being conducted in collaboration with **11 global research institutes**, including institutions in **Switzerland, South Korea**, and the **United States**. Drexel University is representing the U.S. in this groundbreaking initiative, and animal testing will begin by the **end of this year**, marking a significant step toward human trials.
### **Future Possibilities:**
Researchers believe that these nano-robots could not only **treat blocked heart arteries** but also hold the potential to **treat deadly diseases like cancer**. This invention is set to open a new chapter in medical science, with hopes that in the coming years, millions of people could avoid expensive and painful treatments like **bypass surgeries or stent implants**.
