ABSTRACT
Nanotechnology is considered as a "new technological revolution." More generally, nanotechnology includes many structures such as carbon nanotubes, nanocrystals, quantum dots, nanofibers, nanoporous filters, nanowires, metal oxide nanoparticles, dispersion of nanoparticles and polymer nanocomposites. Richard Feynman, Nobel Prize Physics in 1965, was the first to refer to the possibilities of nanoscience and nanotechnology in a speech at the Congress of the American Physical Society in 1959. The term Nanomedicine refers to the application of the nanotechnology to the diagnosis and treatment of diseases. In this field, the use of nanostructured materials, biostructures and nanodevices is studied to improve biomedical procedures and systems. Nanotechnology applied to medicine and pharmacokinetic has allowed the creation of drug delivery nanosystems by using nanoscale devices capable of penetrating cell membranes and pores and releasing the drug in a minimally invasive manner. There are various types of nanoparticles that have been developed as drug delivery systems, such as: liposomes, micelles, dendrimers, nanotubes and polymer conjugates.
