This article provides a brief overview of the preparation process and evaluation of nano-emulsions as drug carriers for enhancing therapeutic agent delivery. For the preparation of nano-emulsion, several techniques such as microfluidization, high-pressure homogenization, low energy emulsification, and solvent evaporation method and parameters such as droplet size analysis, viscosity determination, drug content, refractive index, pH, zeta potential, transmission electron microscopy, thermal stability, release, and in vitro skin permeation study will be used. As a result, the focus of this review is on the advantages of nano-emulsion, various methods of preparation, characterization techniques, and the various applications of sub-micron size emulsion in various areas such as various routes of administration, chemotherapy, cosmetics, and so on.
