ABSTRACT:
During last two decades, considerable attention has been given to the development of novel drug delivery system (NDDS). Drug particles in nanometer size range have unique characteristics that can lead to enhance performance in a variety of dosage forms. Nanoparticulate drug delivery system may offer platform of advantages over conventional dosage forms, which includes improve efficacy, reduced toxicity; enhance biodistribution with improved patient compliance. Although fields to develop nanotechnology-based efficient drug delivery systems extend into all therapeutics classes of pharmaceuticals, many therapeutic agents have not been successful because of their limited ability to reach the target tissue. Functionalized carbon Nanotubes (f-CNTs) are emerging as new tools in the field of nanobiotechnology and nanomedicine. Carbon Nanotubes (CNTs) have become strongest candidates mainly in the field of biomedical engineering, biotechnology; defense research and pharmaceutical nanotechnology after their discovery in 1991.Ever since, the discovery of CNTs several ways of preparing them has been explored. The introduction and delivery of DNA, proteins, or drug molecules into living cells is important to therapeutics. Inorganic nanomaterials, including nanocrystals, nanotubes, and nanowires, exhibit advanced physical properties promising for various biological applications, including new molecular transporters.
