Abstract:
1. A method of producing a nanoemulsion, comprising: preparing a droplet solution comprising first and second molecular species, said droplet solution being in a fluid phase, wherein said first molecular species is soluble in said second molecular species; forming a first plurality of fluid droplets from said droplet solution in a bulk fluid to provide a first emulsion, said first plurality of fluid droplets having a first ensemble average radius that is greater than about 100 nanometers in said bulk fluid, wherein said first molecular species of said fluid droplet solution is at least partially soluble in said bulk fluid and said droplet solution is at least partially immiscible in said bulk fluid; performing an extreme emulsification of said first emulsion to provide a first nanoemulsion comprising a second plurality of fluid droplets having a second ensemble average radius that is less than about 100 nanometers in said bulk fluid; subjecting said first nanoemulsion to an environment to provide a second nanoemulsion comprising a third plurality of fluid droplets having a third ensemble average radius that is less than said second ensemble average radius due to said first molecular species migrating out of said second plurality of fluid droplets to said bulk fluid; and collecting said third plurality of fluid droplets having said third ensemble average radius to provide said nanoemulsion having reduced fluid droplet sizes.
