Nanorobotics

---

Nanorobotics is a new field focused on building tiny machines or robots made up of parts that are as small as a nanometer, or very close to that size. Nanorobotics is a branch of nanotechnology focused on creating and building tiny robots, usually between 0.1 to 10 micrometers in size. These robots are made from very small parts, often at the molecular or nanoscale level. The terms Nanobots, Nanoids, Nanites, nanomachines or nanomites are used to describe this device.Nanorobots are small machines designed to treat diseases in humans and other organisms. A large number of these nanobots are required to effectively carry out both microscopic and macroscopic tasks.There are three main types of nanorobots: Respirocytes, Microbivores, and Clottocytes. Respirocytes act like artificial red blood cells. They can carry a lot more oxygen than real red blood cells. This can be very useful for people with anemia. Microbivores function like artificial white blood cells, acting as "nanorobotic phagocytes." They engulf and break down bacteria present in the bloodstream. Clottocytes work like artificial platelets, helping blood to clot faster. They can stop bleeding in about 1 second, even in the case of large wounds. Now-a-days Nanorobots are being used in many areas. In electronics, they help make extremely small and complex circuits on electronic chips, allowing more components to fit into a tiny space. Nanorobots play an important role in the medical field by helping with early detection of diseases and delivering drugs directly to specific areas in the body. They are used in treating cancer, dissolving blood clots, breaking down kidney stones, healing wounds, improving surgical procedures, and developing advanced medical instruments. They are also useful for monitoring how medicines move through the body, managing diabetes, and supporting overall health care. In the future, medical technology is expected to rely more on nanorobots placed inside the body to work directly at the level of individual cells.
