Kill Tumors
The concept of tiny, microscopic robots that can carry out difficult surgical procedures was mostly restricted to science fiction until recently. That's no longer the case since a range of medical nanobots have proliferated as a result of recent advancements in nanotechnology and robotics. The potential medical uses for tiny machines that might be programmed to perform anything are only a person's imagination.
While not all of them will likely be accomplished anytime soon, nanobots can already do several tasks. In a 2018 study that was published in Nature Biotechnology, researchers created microscopic robots that could swarm tumor cells and clog their blood supply. These nanobots were successfully tested on mice and were created by folding DNA fragments, a process known as DNA origami, and a blood-clotting enzyme called thrombin. Naturally, the architecture of people and mice differs somewhat, so it would take some time before nanobots could totally destroy cancer. Although the research is still in its early stages, these findings are encouraging.
