A person who is diagnosed with cancer will be offered a new alternative to chemotherapy because the traditional treatment of radiation that kills not just cancer cells but healthy human cells as well, causing hair loss, fatigue, nausea, depression, and a host of other symptoms. The application of nanorobotics can be considered as the better solution to this problems. Nanorobots are nanoelectromechanical systems designed to perform a specific task with precision at nanoscale dimensions. This technique involves the development of fully functional nanorobots capable of sensing, decision making, and actuation. From a bio inspired perspective, those in nanorobotics, including core design, propulsion and power generation, sensing, actuation, control, decision making, and system integration. The core of the nanorobots is a polysaccharide based nanoparticle, sensing and actuation ensure that it is capable of sensing and recognizing the cancer cell. These nanorobots may aid in cancer therapy, site-specific drug delivery, circulating diagnostics, advanced surgery, and tissue repair. One of the major advantages of nanorobots is it will not affect healthy cells in human body. Using strategies inspired from microorganisms, potential bioengineered nanorobots can be used for cancer therapy.
