Magnetic Nanorobots:
Magnetic nanorobots are microscopic, externally powered machines made from or coated with magnetic materials like iron oxide. Guided by magnetic fields from outside the body, they can be precisely steered to navigate blood vessels or tissues without an onboard power source.They mimic the corkscrew motion of bacteria, using a tiny, helix-shaped tail that functions like a propeller.A magnet attached to this helix allows it to be controlled and propelled by external magnetic fields, enabling a drilling motion to navigate through complex biological environments.Their structure is biocompatible, made of silica and iron, and can be coated with cancer drugs, effectively turning them into targeted delivery trucks.
