The creation of nanoemulsions involves several techniques, which typically include high-energy methods and low-energy methods. High-energy methods, such as high-pressure homogenization and ultrasonication, use mechanical forces to break down droplets into the nanoscale. Low-energy methods, like phase inversion temperature and spontaneous emulsification, rely on the intrinsic properties of the system, such as changes in temperature or composition, to form nano-sized droplets.
