The Biomedical Applications of Nanorobots - A mini Review

Abstract

Nanotechnology is the most advanced research technique used in different fields of science like agriculture, food, therapeutics, energy and so on. Nanorobots are small scale materials having wide variety of uses in the field of diagnosis and therapeutics. Nanorobots or nanobots are self-propelled nanomotors and nanodevices which are biodegradable. These are made from bio-nano components that have the ability to carry the drug cargo to the target site and deliver these loaded drugs to the diseased cells. We can programme these nanobots for the transport of molecular payloads and can execute many site-specific functions, in vivo health monitoring etc. Diabetes is the most common health condition where the glucose or sugar levels are high in the body. On the other hand, cancer is also a life-threatening disease where the cell undergoes uncontrolled proliferation. Cancer stem cells must be killed to control the cancer because they can migrate through metastasis to other sites of the body and spread the malignant tumor. These tumors have rapid vascularization and if the blood supply can be restricted in these blood vessels, the tumor cells can be killed. Application of nano robotics in monitoring the blood glucose, killing the cancer cells, its advantages and challenges are reviewed in this paper.
