Applications of Nanotechnology in the Field of Medicine

Nanotechnology is an emerging branch of science, which deals with the designing of tools and devices of size 1–100 nm, with unique functions at the cellular, atomic and molecular levels. It is a multidisciplinary field that has emerged due to the interaction of engineering, physics, chemistry and biology. This new field is a result of rapid advances in science and technology, which is creating new opportunities for advancing medical sciences and disease treatment pertinent to human health care. Nanotechnology and nanomedicine are considered as complementary disciplines, which aim to better human life. Applications of nanotechnology to medicine and physiology consist of materials and devices, which are designed to interact with the body at molecular scale with a high degree of specificity. This finally results in their potential use into targeted cellular and tissue-specific clinical applications and helps in achieving maximal therapeutic efficacy with minimal side effects. Presently, nanotechnology and nanoscience are aiming particularly to design and formulate to act as a platform to expand the market for many drugs and forming a basis of high profit to industry. Thus, in the present scenario, nanotechnology is proving beneficial in solving problems in different fields of medicine. In this review, we discuss the potential use of nanotechnology in clinical applications.
