Nanobots, or nanorobots, are tiny machines that can perform specific tasks at the nanoscale. In medicine, nanobots have the potential to revolutionize surgery, diagnostics, and treatment. For example, they can be programmed to seek out and destroy cancer cells, repair damaged tissues, or deliver drugs to precise locations within the body. Although still in the experimental stage, nanobots hold promise for minimally invasive procedures and personalized medicine.
