Researchers achieved a breakthrough in bladder cancer treatment using self-propelling nanorobots powered by urea in January. Conducted on mice at the Institute for Bioengineering of Catalonia and CIC biomaGUNE in Spain, the nanomachines targeted bladder tumors with a radioisotope, resulting in a remarkable 90% reduction in tumor size after a single dose. This new approach holds potential for more effective and cost-efficient treatment, marking a significant milestone in medical innovation.
