From the ancient time it has been the endeavor of the physician and the apothecary to provide patients with the best possible forms of medicine, for recovery from disease faster and completely within minimum adverse effects. Paul Ehrlich in1902 initiated the era of targeted delivery,who proposed drug delivery to be as magic bullet. An ideal drug delivery system is that fulfils the objective of spatial placement and temporal delivery resulting maximized therapeutic effect and least toxicity. With the progress in time and growth of science and technology, the dosage forms have evolved from simple mixtures and pills, to highly sophisticated technology intensive systems, which are known as novel drug delivery systems (NDDS). (1) A different approaches have materialized into various forms of NDDS such as microemulsions, multiple emulsions, liposomes, niosomes, micospheres, pharmacosomes, virosomes, dendrimers, etc.. Most often the problems associated with these delivery systems are their stability and predictability in biological systems which reduce their clinical potential, although each one is associated with its own strong points. Nanotechnology is a rapidly expanding field today. According to the National Nanotechnology Initiative (U.S) nanotechnology is broadly defined as the understanding and control of matter at dimensions of roughly 1 to100 nanometers, where unique phenomena enable novel applications.
