Nanorobots are tiny machines designed at the nanoscale, typically measuring between 1 and 100 nanometers. They can perform specific tasks, such as delivering drugs directly to cells, repairing tissues, or detecting diseases. Their small size allows them to navigate through the human body and interact with biological systems in ways that larger robots cannot. These robots are often made from materials like carbon, silicon, or DNA, which can be engineered to perform various functions. Researchers are exploring their potential applications in fields like medicine, environmental monitoring, and manufacturing, aiming to improve efficiency and precision in these areas.
