Nanotechnology in drug delivery

Nanotechnology is science of theme and material that deal with particle size in nanometers. Nanotechnology has received a lot of attention because of its future potential. Nano technology offers the advantage of protecting drugs from degradation, reduce the number of doses required. It is a revolutionary technique that which utilizes devices and molecules in the range of 1-100 nanometers. Particles exposed to nanotechnology exhibits superior characteristics including resistance to settling, higher saturation solubility state, protection from decomposition, enhanced drug release, increased adhesion to biological membranes, improved strength and reduced weight, enhanced absorption and improved chemical reactivity as compared to their larger scale corresponding item. There are different techniques for the preparation of nano drug delivery systems like nanoparticles, solid lipid nanoparticles, nanocrystals, nanosuspensions, Nano emulsions. The goal of Nano technology is to develop useful formulation to treat diseases in patients. Although, nanotechnology is performing good role in modern advancements from cell phones to medicines, yet it is necessary to consider their negative part as well that could be dangerous if not given proper attention.
