ABSTRACT
Nanotechnology is the manipulation of materials or devices at the nanometer scale (one billionth of a meter), that is, at the level of individual atoms and molecules. e word “nano” is derived from the Greek word for dwarf. e timescale of nanotechnology history began with a talk given in 1959 by physicist Richard Feynman, titled “ ere’s plenty of room at the bottom.” e wide perspective of nanotechnology is applicable to all spheres of life. Nanotechnology has an integral role in the rapid advancement of the medical sciences. e emerging and growing eld of nanotechnology in the area of medical applications can be termed as nanomedicine, which account for more than 50% of all publications and patent ling worldwide (Wagner 2005). erefore, much attention has been paid for intense research on nanotechnology-mediated drug delivery and drug targeting.
