Abstract

Nano technology, a newly evolved discipline aims the creation, manipulation and application of structures in the nanometer size range. Nanotechnology has tremendous applications in various field of science; its importance has been also realized in drug delivery via nanoparticle. Drug delivery is a very efficient process, but it is facing different challenges. For the effective drug delivery it requires stabilization, extended circulation and the proper targeting of the drug. In this regard use of nanoparticle has evolved a best alternative. A variety of nanoparticles like metal based, lipid based, polymer based etc. are extensively studied for their role in drug delivery. Nanoparticle can easily enter most cells and circulate through the body, are suitable for targeted delivery vehicles to carry large doses of chemotherapeutic agents or therapeutic genes into the target site. Among the newly developed nanomedicine and nanodevices such as quantum dots, nanowires, nanotubes, nanocantilevers, nanopores, nanoshells, the nanoparticles are the most promising applications. The present article reveals the medicinal aspects of nanotechnology especially nanoparticle and highlighting its importance in drug delivery systems.
