Unlocking the Potential: The Emergence of Nanobots in Future of Oncology

The treatment of cancer in the recent era has undergone quite a lot of developments, one of such is the emergence of Nanobots. Until its emergence, the traditional treatment of cancer primarily relied on the use of chemotherapeutic drugs and surgery, which in majority of the cases resulted in catastrophic side effects and in some cases into Multi drug resistance. Nanobots over the years have proved to be the most reliable means of cancer treatment thanks to its high specificity towards carcinogenic cells, exceptional efficiency and minimal side effects. These Nanobots consist of an outer shell, a propeller, power source, Sensors, payloads, nano camera, nano lasers and communicators. Extensive research in this field suggests that these nanobots can be easily converted into completely autonomous bio computing agents that are capable of executing complex Boolean logic gates. So, these nanobots exist in two states: Off and On. Initially they remain in off state, completely incapable of releasing drugs. Upon reaching the target organs through the bloodstream, they get converted into on state by receiving external signals and release the payloads (drugs) to perform the specific functions as discussed below before reverting back to their Off state. Eventually, they get excreted out. Despite their promise, nanobots are not without challenges. Issues such as biocompatibility, precise navigation and targeting, potential immune responses, and the ethical implications of their use present significant hurdles. We herein also discuss their potential challenges and future prospect of them being used as a successful medium of cancer treatment.
