Nanometric-Scaled Emulsions (Nanoemulsions)

Nanotechnology, shortened to nanotech, is the study of the controlling of matter on an atomic and molecular scale. Generally, nanotechnology deals with structures sized between 1 to 100 nanometer in at least one dimension and involves developing materials or devices within that size. The use of nanotechnology in the field of pharmaceutics and drug delivery has grown over the last few years, so remarkably that the pharmaceuticals developed on the basis of this technology are termed as Nanopharmaceuticals. Among the nanopharmaceuticals currently being used or under investigation, one can mention nanoemulsions, nanosuspensions, nanospheres, carbon nanotubes, micellar nanocarriers (polymeric micelles), nanocapsules, lipid nanoparticles, self-nanoemulsifying systems, dendrimers, etc.
