Nanoemulsion

Nanoemulsion refers to a system of oil-in-water or water-in-oil where the droplets of the dispersed phase are extremely small, typically in the nanometer scale, ranging from 20 to 200 nanometers. These emulsions are clear or translucent with unique properties due to their small droplet size, such as high surface area and kinetic stability. Nanoemulsions are formed using high-energy emulsification methods like ultrasonication or high-pressure homogenization, which overcome the interfacial tension between the two immiscible phases and create the tiny droplets. Because of their small size, these droplets can remain stable for a long time without coalescence or sedimentation. Nanoemulsions have gained considerable attention in various fields including pharmaceuticals, cosmetics, food technology, and environmental remediation due to their enhanced solubility, bioavailability, and controlled release of active ingredients. They are particularly useful for the delivery of hydrophobic compounds and have been explored for their potential in targeted drug delivery, vaccine development, and cancer therapy. The unique characteristics of nanoemulsions make them an important subject of research in nanotechnology and material science, as scientists continue to explore their potential applications and the mechanisms behind their stability and formation.
