Nanoemulsions are submicron sized emulsions which are clear, transparent and thermodyanmically stable with a droplet size ranging from 5-200nm. acts as drug carriers for improving the delivery of therapeutic agents. Nanoemulsion are isotropic liquid mixtures of oil, water, surfactant and co-surfactant. Nanoemulsions have widespread applications in different fields such as pharmaceutics and food technology. Nanoemulsion offers a promising vehicle for increasing the aqueous solubility of poorly water-soluble drugs. The development of nanoemulsions aimed at improving the required bioavailability levels of therapeutic agents. This review mainly discusses about the preparation methods, characterization and applications of nanoemulsions.
