Nanotechnology is a field of research and innovation concerned with building things, those are generally, materials and devices on the scale of atoms and molecules. It involves the understanding and control of matter at the nanometre-scale. Nanoscale deals with the dimensions between 1 and 100 nanometres.
Nanotechnology drug delivery applications takes place through the use of designed nanomaterial as well as forming delivery systems from Nanoscale molecules such as liposomes and enhances the ability to transfer the drugs that are poorly water-soluble and provides site-specific targeting to overcome drug accumulation within healthy tissue.
