The branch of technology that deals with dimensions and tolerances of 1-100 nanometres, especially the manipulation of matter on an atomic, molecular and supramolecular scale, is known as ‘Nanotechnology’. In 1959, the concepts of nanotechnology were first put forward by Richard Feynman, but the actual term ‘Nanotechnology’ was first introduced by Norio Taniguchi in 1974. Since its introduction, nanotechnology has played an important role in advancing almost all areas of science, particularly, drug formulation and delivery. In fact, the area of drug formulation and delivery, where nanotechnology is applied, is now known as ‘Nanopharmaceutics’. As nanoparticles are accepted by cells more efficiently than larger micromolecules, they can be used as effective transport and delivery systems. For medicinal purposes, drugs can either be integrated in the matrix of the particle or attached to the particle surface.
