Nanorobots, engineered devices at the nanoscale, hold immense promise for revolutionizing medical applications. Their potential to navigate the human body at a cellular level opens doors to targeted drug delivery, precision diagnostics, and minimally invasive surgery. This abstract explores the burgeoning field of nanorobotics in medicine, highlighting their potential to overcome limitations of conventional treatments. We will delve into various designs and functionalities of nanorobots, including their actuation mechanisms, targeting strategies, and biocompatibility considerations.
