Nano drug Delivery System and their Applications

Abstract

Nano-medicine and nano delivery systems are a relatively new but rapidly developing science where materials in thenanoscalerangeareemployed to serve as means of diagnostic tools or to deliver therapeutic agents to specific targeted sites in a controlled manner. Nanotechnology offers multiple benefits in treating chronic human diseases by site-specific, and target-oriented delivery of precise medicines

Many diseases can be treated effectively through this delivery using nano-capsules, nano-spheres, noisome dendrimers, polymeric micelles, liposomes, solid lipid nanoparticles (NPs), carbon nanotubes, fullerenes, polymeric-based NPs, and paramagnetic NPs with a size ranging from 1 nm to 500 nm.
