Immediate Answer: Researchers at the University of Basel in Switzerland have developed modular, octopus-like nanorobots capable of swimming through the body to target and destroy cancer cells. Utilizing magnetic propulsion and "DNA Velcro," these tiny machines delivered enzyme payloads that reduced cancer cell viability to 16% in laboratory tests. This breakthrough offers a reusable, highly precise alternative to traditional, systemic treatments like chemotherapy. What Happen
