A breakthrough study published in Science by researchers at ETH Zurich has revealed a new generation of tiny magnetic microrobots capable of delivering life-saving drugs directly to stroke-causing clots and tumour sites with remarkable precision. The study demonstrate s a 95 percent success rate in targeted drug delivery, signalling a major shift in how future doctors may treat some of the world’s deadliest conditions. Current stroke treatments involve administering powerful clot-dissolving drugs into the bloodstream. While effective, these drugs circulate widely and may cause serious complications, including internal bleeding. The microrobot offers a way around this problem. The capsule can be loaded with a clot-dissolving or tumour-fighting drug, which is only released when doct
