Nanotechnology Based Drug Delivery System and its Applications

Nowadays, nanotechnology is considered as one of the most wide spread field of science with its important application in different fields as health, biology, chemistry, etc. in this review article we will discuss applications of nanotechnology in the field of health care, different used techniques and some examples. Nanotechnology, in a blink.
 The definition of nanotechnology is typically stated in Bhushan (2010)
"Nanotechnology literally means any technology on a nanoscale that has applications in the real world. Nanotechnology encompasses the production and application of physical, chemical, and biological systems at scales ranging from individual atoms or molecules to submicron dimensions, as well as the integration o the resulting nanostructures into larger system."
Applications of nanotechnology are very wide and can be found in many fields as biology, chemistry, physics, agriculture, medicine and engineering.Because the field of nanotechnology depends mainly on manipulating and controlling molecules in the atomic level, the field of nanoscience starts to thrive by the invention of the microscope that can magnify molecules and atoms almost 30 years ago.
