Imagine a tiny army of microscopic robots swimming through your bloodstream, monitoring vital signs, detecting diseases, and even delivering targeted treatments. This is not a scene from a science fiction movie but a real and emerging field of nanotechnology. Scientists and engineers are developing nanobots—miniature robots that can be introduced into the human body to revolutionize healthcare. What Are Nanobots? Nanobots are microscopic machines, often measured in nanometers, that can be programmed to perform specific tasks. In the medical field, these bots are designed to navigate through the bloodstream and collect data on various health parameters, such as detecting cancer cells, identifying infections, or measuring glucose levels. How Do They Work? These tiny robots are typically made from biocompatible materials to ensure they do not harm the body. They can be powered by different methods, including external magnetic fields, ultrasound waves, or even chemical re...
