Nanoemulsions are a type of emulsion where the dispersed phase droplets are nanoscale in size, typically in the range of 20 to 200 nanometers. Nanoemulsions are thermodynamically stable and can be prepared using a variety of methods, including high-pressure homogenization, microfluidization, and sonication.
Nanoemulsions have a number of advantages over traditional emulsions, including improved stability, increased transparency, and enhanced bioavailability. They are used in a variety of applications, including food and beverage, pharmaceuticals, cosmetics, and personal care products.
In the food industry, nanoemulsions are used as a delivery system for functional ingredients such as vitamins, antioxidants, and flavors. In the pharmaceutical industry, nanoemulsions can be used to improve the solubility and bioavailability of poorly water-soluble drugs, and to target drugs to specific tissues or cells.
Overall, nanoemulsions offer a promising platform for the development of advanced materials with unique properties and functions.
