In nanotechnology, emulsifiers are used to create and stabilize nanoemulsions, which are emulsions with droplet sizes typically in the range of 20 to 200 nanometers. The emulsifiers reduce the interfacial tension between the oil and water phases, thus preventing the droplets from coalescing. This stabilization is essential for maintaining the uniformity and functionality of nanoscale dispersions. By controlling the size and stability of these nanoemulsions, researchers can tailor their properties for specific applications, such as enhanced solubility, controlled release, and targeted delivery.
