Canadian Researchers Pioneer Liver Cancer Treatment with Magnetic Microrobots
A novel approach using magnet-guided microrobots in MRI devices shows promise for targeting liver tumors more precisely, potentially revolutionizing treatment methods.
- Canadian researchers have developed a new method to treat liver tumors using magnet-guided microrobots, led by Montreal radiologist Gilles Soulez.
- The microrobots, made of iron oxide nanoparticles, are guided by an external magnetic field and can target tumors with high precision, preserving healthy cells.
- An algorithm combines magnetic force with gravity to navigate the microrobots to the tumor site, overcoming previous limitations.
- The approach has been tested on pigs and simulated on patients previously treated with transarterial chemoembolization, showing over 95% compatibility with the navigation algorithm.
- Clinical application is still in the future, requiring further optimization of real-time navigation and modeling of blood flow and magnetic field direction.
