The emergence of nanotechnology in the field of medicines gives the idea of revolution and farreaching supremacy to conventional and traditional practices of diagnosis and medication. Nanomedicine is poised to transfigure and reform the existing medical procedures, with its much safer profile, accessibility being the modest and economical. Nanomedicines with its intriguing properties has exceptionally improved the drug delivery systems. A diversity of innovations in every medical specialty attribute to the potent impact of nano range applications in medicine field. Nanoparticles are generally accepted in the size range of 1-100 nm although nano morphologies above this range are also widely studied in biomedical field. Nanomedicine will face many challenges in future by regulatory agencies and public and is lacking essential data about pharmacokinetic and pharmacodynamics profiles and toxicity of nanoparticles yet is seems that this advanced technology will be proved more promising, novel and revolutionary to the antecedent medical procedures.
