ROLE OF NANOTECHNOLOGY IN MEDICAL SCIENCES: A REVIEW

Shashi Daksh

Abstract


The interface between nanosystems and biosystems is emerging as one of the broadest and most dynamic areas of science and technology, bringing together biology, chemistry, physics and many areas of engineering, biotechnology and medicine. Any damage at molecular or cellular level is the major culprit for disease & ill health. Nanotechnology, “the manufacturing technology of the 21st  century," helps us to build a broad range of complex molecular machines by manipulating matter on an atomic and molecular scale. Nanotechnology is the creation of useful materials, devices and system through the manipulation of matter on an atomic, molecular, and supra-molecular level in the length scale of 1-100 nanometer size. At the nano scale, the physical, chemical, and biological properties of materials differ in fundamental and valuable ways from the properties of individual atoms and molecules or bulk matter .It enables the alignment of atoms in the most effective way in a very limited place. Extraordinary devices can  be created by using this technique.  Molecules could be aligned in such a way as to produce desired result in the areas of strength, ductility, reactivity, conductivity and capacity. This idea facilitates creating devices and structures that would occupy an unimaginably small space and have novel properties and functions because of their small size. The application of nanotechnology in the medical sector is referred as  Nanomedicine. Nanoparticles have potential applications in  the  field  of medical sciences including new diagnostic tools, imaging agents and methods, targeted drug delivery, pharmaceuticals, bio implants and tissue engineering. Drugs with high toxic potential like cancer chemotherapeutic drugs can be given with better safety profile with the utility o f nanotechnology. The aim of the nanotechnology in the medical sciences is to develop new materials and methods to detect and treat diseases in a targeted, precise, effective and lasting way, with the ultimate goal of making medical practice safer and less intrusive.
