Developed by scientists from the Federal Institute Swiss The Zurich-based technology uses tiny magnetic microrobots that precisely deliver drugs to stroke clots and tumors, achieving a success rate of up to 95%. These steerable capsules release the drug only at the target site, reducing side effects and making it possible to treat hard-to-reach areas.
Researchers are developing small robots to treat stroke and tumors
According to what was published in the Times of India, this discovery has been successfully tested on animal models, and it heralds safer and more effective treatments for critical cases. A pioneering study, published in the journal Science, revealed a new generation of tiny magnetic microrobots capable of delivering life-saving medications directly to clots and tumor sites causing strokes with extreme precision.
The study showed a success rate of up to 95% in delivering targeted drugs, indicating a major shift in how future doctors treat some of the most serious diseases in the world. Microrobots provide a targeted drug for safer and more effective treatment. Current stroke treatments include giving powerful drugs that dissolve clots in the bloodstream. Despite their effectiveness, these drugs are widespread and may cause serious complications, including internal bleeding. A microscopic robot offers a solution to this problem.
The capsule can be filled with a clot-busting or tumor-fighting drug, which is only released when activated by doctors using a high-frequency magnetic field. The magnetic nanoparticles heat under this field, melting the gel shell and releasing the drug precisely where it is needed. This highly focused approach can dramatically reduce side effects, allow for lower doses of the drug, and also makes it possible to treat sensitive or hard-to-reach areas, such as blood vessels within the brain.
Professor Bradley Nelson, a leading expert in the field of microrobotics at the Swiss Federal Institute of Technology in Zurich, explained that magnetic fields are particularly suitable for medical procedures because they are able to penetrate deep into the body without damaging tissue.
