Researchers from the Institute for Bioengineering of Catalonia (IBEC) and collaborators have successfully treated bladder tumors in mice using urease-powered nanobots. The testing consisted of the administration of 18F-nanorobots to tumor-bearing mice divided into four groups depending on tumor volumes using a group of non-tumor-bearing mice as control. Importantly, the therapy remained in the bladder with only a very small proportion of radioactivity seen in other organs. The results were published in Nature Nanotechnology on Jan. 15, 2024.
